Russia's Pacific Fleet has launched a week-long series of exercises with more than 40 ships and up to 20 aircraft taking part, Russian news agencies quoted the defence ministry as saying.

The ministry statement said the exercises, taking place from 3 to 10 June, would involve, among other matters, "groups of ships together with naval aviation taking part in search operations for [enemy] submarines".

Russia is now achieving "tactical success" in the eastern Donbas region of Ukraine, but it's come at a "significant resource cost", the UK's Ministry of Defence has said in its latest intelligence update., external

Questions remain around Moscow's decision to concentrate so much of its "force and fires" on a single part of the overall campaign.

Looking back at the 100 days since Russia invaded its neighbour, the MoD also reminds people that Vladimir Putin's original plan - to seize the capital Kyiv and topple Ukraine's government - has failed.

However, 90% of Luhansk - part of the Donbas region - is now controlled by Russia, the update said. And it is likely Putin will have complete control of the area in the next two weeks.

TV viewers in Russia see only the Kremlin's version of events in Ukraine.

From initially being told nothing of the plans to invade, to repeated claims about the need to "denazify" Ukraine, Russians are being fed a different narrative to the rest of the world.

Take a look at how Moscow's coverage has changed in the 100 days since the war began.

Nato Secretary-General Jens Stoltenberg has said Western countries need to "prepare for the long haul".

Speaking to reporters after meeting US President Joe Biden at the White House on Thursday, Stoltenberg said Nato must continue to support Ukraine in what was becoming a long and sustained conflict:

"We just have to be prepared for the long haul because what we see is that this war has become a war of attrition where the Ukrainians are paying a high price for defending their own country on the battlefield, but also where we see that Russia is taking high casualties.

"Our responsibility is to provide support to Ukraine. Most wars - and also most likely this war - will at some stage end at the negotiating table, but what we know is that what happens around the negotiating table is very closely linked to the situation on the ground, on the battlefield, so we need to help them, to support them, so they can achieve the best possible outcome of this conflict."

We're resuming our live reporting on Russia's war with Ukraine. Here are the latest developments:

Grave milestone: It's 100 days since Russia invaded Ukraine on 24 February. On the eve of the anniversary, President Zelensky said up to 100 of his soldiers were dying each day as they resisted Russia's push to control the country's eastern region.

On the ground: Russian troops are continuing their bid to take the east - particularly the city of Severodonetsk - as they try to break the last of Ukraine's defences there.

Fifth of territory: Russia now occupies a fifth of Ukraine's territory, Zelensky said on Thursday. Before the war, Russia and Russia-backed separatists accounted for less than 10% of Ukraine's make up.

Grain exports: After weeks of back and forth, Russia's defence ministry has said vessels carrying grain can leave Ukraine's ports in the Black See via "humanitarian corridors" - but it's not known when, or if, the exports will resume.

Artillery: President Zelensky told a forum in Slovakia that the supply of more Western weapons could turn the outcome of the war in Ukraine’s favour. It comes after the US this week pledged $700m (£556.7m) worth of military aid, including advanced rocket systems.

We'll be back again tomorrow - here's our story rounding up today's main news.

We'll bring our live coverage of the Russian invasion of Ukraine to a close shortly - so here is a reminder of what has been happening.

• Ukraine's President Zelensky has said 20% of his country's territory is now occupied by Russia
• The Russian army is trying to break Ukraine's remaining defence in the eastern city of Severodonetsk, where 80% of the city has already fallen to Russian troops
• Oil producing nations have agree to boost their output following the EU's move to cut dramatically the amount it gets from Russia
• EU ambassadors have approved the bloc's sixth wave of sanctions but have removed Orthodox Church Patriarch Kirill from the list, following objections from Hungary
• Meanwhile, the US has announced further sanctions on Russian individuals
• After weeks of diplomatic efforts, Russia's defence ministry says that vessels carrying grain can leave Ukraine's ports in the Black Sea via "humanitarian corridors" - but it's not known when, or even if, the exports will resume

We reported earlier on the US and UK sending rocket systems to Ukraine.

Now Sweden says it will send extra weapons to Kyiv’s forces, in a new package worth 1bn kronor (£81m; $102m), including coastal anti-ship missiles.

The Swedish-made Robot 17 missiles, plus 5,000 anti-tank launchers and AG 90 assault rifles come on top of arms already sent by Sweden.

Denmark has already sent Harpoon anti-ship missiles to Ukraine, which is beefing up the defence of Odesa, a vital port. Russia captured the port of Mariupol - now in ruins - after months of bitter fighting.

Russia’s invasion prompted Sweden to break a neutrality policy dating back decades – previously Sweden did not send arms to nations at war.

Last month Sweden and neighbour Finland decided to join Nato – a watershed moment in the Nordic countries’ defence stance.

Russia's defence ministry says that vessels carrying grain can leave Ukraine's ports in the Black Sea via "humanitarian corridors", with Russia ready to guarantee their safety, Reuters quotes the Interfax news agency as saying.

The ports have been largely blocked for exports since the invasion began in February. There have been international diplomatic efforts to restore the routes, including an appeal for action by the UN last month.

Ukraine is a major exporter of grain and its inability to export crops has led to global food prices soaring. But it's not known when - or even if - the corridors will be operational.

The Moldovan parliament has approved a ban on Russian news programmes in a bid to prevent Moscow's propaganda.

Moldova, once a Soviet republic, sits on Ukraine's south-western border. It does not share a border with Russia, but is close to some of the regions currently occupied by Russian forces in Ukraine's south.

The Russian invasion of Ukraine has heightened tensions in Moldova, which is seeking EU membership and has a Moscow-backed separatist region, Transnistria.

Russia supports separatists in Transnistria and has around 1,500 troops there.

Televising Russian news broadcasts has been banned since the start if the war but parliament formally approved the legislation on Thursday.

Moldovan TV will now only be allowed to air entertainment programmes from Russia and not political shows. The new legislation also imposes fines and other penalties for broadcasting misinformation.

A Russian-operated plane has been seized in Sri Lanka shortly before it was due to return to Moscow with nearly 200 people on board, airport bosses said.

The Aeroflot Airbus A330 - which had arrived from Moscow on Thursday - was prevented from returning following an order from Colombo Commercial Court, an official for Bandaranaike International Airport, which is just north of the capital, told the AFP news agency.

Aeroflot, Russia's flagship carrier, halted all international flights in March following Western sanctions over the invasion of Ukraine, but re-started operations to Colombo in April.

It was not immediately clear if the detention of the flight was related to sanctions.

Passengers and crew were taken to hotels, representatives for the airport said.

Russia-imposed authorities in the occupied Zaporizhzhia region have said the Ukrainian state's property and resources will be "nationalised".

Andrei Trofimov, the deputy head of the Moscow-imposed administration, said a decree had been signed for the nationalisation of Ukrainian property, according to the Russian Interfax news agency.

Interfax quoted Trofimov as saying that the nationalisation would affect land, natural resources, facilities in strategic sectors of the economy, as well as property owned by Ukraine as of 24 February - the day when Russia launched its invasion of the country.

"The decree was signed in order to meet state needs related to improving the overall efficiency and social orientation of the economy, as well as to preserve the national heritage for residents of the Zaporizhzhia Region," he said.

Earlier, we reported that Ukrainian authorities could turn off the nuclear plant in the region if Kyiv loses control of operations of the site.

Ukraine's President Zelensky said today that Russian forces are now in control of 20% of Ukrainian territory.

He said almost 125,000 sq km (48,260 sq miles) was now in Moscow's hands. That includes Crimea and parts of eastern Ukraine that Russian proxy forces seized in 2014, which make up roughly 7% of Ukraine's territory.

Russian troops now control most of Severodonetsk. Taking the city would mean Russia controls almost all of Luhansk, part of Moscow's bid to capture the wider Donbas region.

But the Institute for the Study of War (ISW) said a possible Ukrainian withdrawal from Severodonetsk would be "strategically sound" as the city's loss would be "largely symbolic".

Further north, Ukraine has successfully pushed Russian forces away from Kharkiv, although the city was shelled last night.

In southern Donetsk, Russia is now fully in control of the port city of Mariupol, after a siege lasting more than two months came to an end on 20 May.

Analysts say the fall of the city may enable Russian units to join the fight in other areas such as Zaporizhzhia, where the shelling of Ukrainian forces is ongoing.

A top Ukrainian general has insisted there is no need for his troops to withdraw from the eastern city of Severodonetsk, even though Russia is trying to surround them.

Olexiy Gromov, of the Ukrainian General Staff, said the enemy was bent on surrounding Ukrainian troops inside Severodonetsk, throwing all its resources into achieving that single goal.

Fierce street fighting has continued in the eastern city with Russian troops trying to capture it.

In that case - he said - the Ukrainians would mount defence within residential areas and along the Siverskyi Donets river that separates it from Lysychansk.

Contradicting earlier statements from officials, General Gromov said that at this point, there was no need for Ukrainian troops to withdraw.

As we reported in the post below, the UK and the US are sending rocket launchers to Ukraine.

Earlier, Ukraine's deputy defence minister insisted his country is still fighting "an exclusively defensive war" - in response to questions about whether US equipment could be used to target Russian territory outside Ukraine.

The four US High Mobility Artillery Rocket Systems (HIMARS), part of a military package promised by President Biden this week, have a range of 45 miles (70km), double that of the rockets currently in Ukraine's inventory.

Hanna Malyar was clear that Ukraine's position had not changed and the weapons would only be used in self-defence: "We always state this," he told reporters.

Meanwhile, Russian forces are continuing their onslaught in the Donbas area, with an assault on the east Ukrainian village of Berestove.

Berestove is located on the main road linking Lysychansk to the rest of Ukraine. Lysychansk and its twin city Severodonetsk are the easternmost cities still in Ukrainian hands and remain key targets for Russia.

If Russian forces seize the two cities, they would then control all of the eastern Luhansk region, which taken together with the neighbouring Donetsk region makes up the area known as Donbas.

A top aide to Ukrainian President Volodymyr Zelensky says the UK has agreed to supply the M270 multiple-rocket system (MLRS) to Ukraine, seen as a military game-changer.

"The M270 long-range rocket systems that Ukraine will receive from Britain, together with the American HIMARS, will significantly strengthen our armed forces. We are grateful to the allies for them," presidential chief of staff Andriy Yermak said.

"We persistently explain to our allies why weapons for Ukraine today can not only help [us] liberate all our territories but also prevent many threats to the West. And it works," he wrote on the Telegram messaging service.

It is not yet clear how many M270 systems the UK will send.

But CNN quoted a UK government statement saying the rockets’ range would be up to 80km (50 miles), offering “a significant boost in capability for the Ukrainian forces”. Ukrainian troops will get training on them in the UK.

The move was “co-ordinated closely” with the US decision to provide Ukraine with HIMARS, a similar system, the statement said.

“The UK stands with Ukraine and has taken a leading role in supplying its heroic troops with the vital weapons they need to defend their country,” it said.

HIMARS (High Mobility Artillery Rocket System) is a more agile multiple rocket launcher. It fires six guided rockets, but the US-built M270 can fire 12.

The two systems are superior in range and precision to the multiple-rocket systems which Russia is using to pound cities in eastern Ukraine.

The UK has sent large quantities of weapons to Kyiv's forces already, including:

• More than 5,000 light anti-tank weapons (Nlaw). They are short-range, easy to position and require little training. Analysts say they have been very effective against Russian tanks
• Hundreds of Brimstone missiles for use against tanks, artillery and boats such as landing craft
• 120 armoured vehicles, including Mastiffs
• Heavy-lift drones
• Several anti-aircraft systems including Starstreak missiles, and Stormer vehicles to carry Starstreaks.

If you are just joining our coverage - or need oa reminder - here are some of the main developments today:

• Oil producers have agreed to boost output in July and August, following the European Union's move to block most imports from Russia. But the increase will only partially make up for decreased Russian output
• The US has announced a new round of sanctions against Russian individuals, including several prominent Russian government officials
• Fierce street fighting continues in the eastern city of Severodonetsk, where 80% of the industrial city has fallen to Russian forces
• Ukrainian President Volodymyr Zelensky has said that Russia now controls 20% of his country's territory, during an address to the Luxembourg parliament
• Russian forces have also shelled the city of Kharkiv overnight - and carried out a missile strike in Lviv

As we reported earlier, global oil producers have agreed to increase supply, in an attempt to offset partially falls in Russia output.

And Russia has now warned that European consumers will be the first to suffer after Brussels introduced a partial embargo on Russian oil.

"As a result of these decisions, European consumers will suffer above all," Russian deputy prime minister Alexander Novak said in televised remarks.

He added there may be a "big deficit" of oil products in the European Union.

The European Union has agreed to block most Russian oil imports by the end of 2022.

The ban will affect oil that arrives by sea - around two-thirds of imports - but not pipeline oil, following opposition from Hungary.

Poland and Germany have also pledged to end pipeline imports, meaning a total of 90% of Russian oil will be blocked.

Russian lobbyists have been barred from entering the European Parliament, the head of the chamber says.

Europeans had to protect themselves from the Kremlin's influence and propaganda over the war in Ukraine, Roberta Metsola said on Twitter.

"Effective immediately, Russian company representatives are no longer allowed to enter," Metsola stated.

Russian President Vladimir Putin has granted chess grandmaster Sergey Karjakin a state award after he was suspended by the discipline's international governing body for supporting Moscow's invasion of Ukraine.

Putin granted him a medal "For Merit to the Fatherland", a distinction for Russians who have made outstanding contributions in their fields, according to Reuters.

Karjakin, who challenged Magnus Carlsen for the world title in 2016, is a Putin supporter and defended Russia's decision to send troops into Ukraine on social media.

This prompted the International Chess Federation (FIDE) to suspend him for six months for breaching its code of ethics in March, something the Crimea-born player described as shameful.
