We're pausing our live coverage of the war in Ukraine shortly. But before we go, here's a recap of today's main developments:

• Russia has unleashed two waves of missile strikes across Ukraine, with strikes reported in the capital Kyiv, as well as the eastern Kharkiv and western Lviv regions, and other parts of the country
• At least five people have died and 39 were injured - including seven children - after a missile hit a residential building in the city of Dnipro, the region's governor has confirmed
• Emergency services are working to rescue people from the rubble, with 20 pulled from the smoking remnants of the block of flats so far
• Energy Minister Herman Halushchenko has warned of "difficult days" ahead after Russian missile strikes damaged energy facilities in six Ukrainian regions
• Debris from a missile strike on western Ukraine has also been found in neighbouring Moldova
• Meanwhile, UK Prime Minister Rishi Sunak has confirmed the government will provide Challenger 2 tanks to Ukraine in a call with Volodymyr Zelensky
• Thanking the UK, Ukraine's president said the Challenger 2s both strengthen them on the battlefield and "send the right signal" to other allies
• The supply of main battle tanks to support Ukraine could mark a significant moment if other allied nations follow suit to supply them, the BBC's defence correspondent Jonathan Beale says

The scene at the devastated apartment block in Dnipro is one of profound shock and frantic action.

A sizeable crowd has gathered to watch, while others have joined rescue workers in a desperate search for survivors. The smouldering heap of wreckage, several storeys high, is a hive of activity.

There are urgent calls, human chains of volunteers clearing rubble and torch beams piercing thick clouds of dust and smoke.

As night falls and the temperature drops, the official number of dead and injured is climbing inexorably. It’s likely to be the worst attack here in months.

There’s no information yet on what caused such devastation. The apartment block is some distance from the nearest power facility.

On a day when Russia seemed intent, once again, on targeting Ukraine’s energy grid, this could have been one of the less accurate missiles in Russia’s arsenal, or something brought down by Ukraine’s air defences - although on the face of it, this seems a less likely explanation.

It’s been two weeks since the last wave of Russian attacks on Ukraine’s power grid. Officials, in the West and in Ukraine, had begun to wonder if Russia’s “energy war” might be coming to an end, due to a possible shortage of suitable missiles and the evident fact that the strategy has yet to break Ukraine’s spirit.

Today’s attacks suggest Moscow still thinks it’s a tactic worth pursuing.

As we reported earlier, the UK has said it is to send tanks to Ukraine. We have more about that decision:

Two days ago, the Ukrainian defence minister told me he was confident his country would receive “tanks, fighting aircrafts or jets and long-range weaponry”.

This, according to Oleksii Reznikov, was the result of a change in the “thinking approach” by some Western countries, once concerned that military assistance could be seen as an escalation by Russia. Things were changing, he said.

The news from London, which is likely to put pressure on other allies to make similar moves, comes as Ukraine and Russia seem to be preparing for new offensives in the spring.

The supply of modern weapons and equipment by the West has been vital for Ukraine in its fight against invading Russian forces. Russian figures, meanwhile, have argued this means they are fighting Nato in Ukraine.

But Reznikov dismissed concerns that the announcements could trigger a Russian response, despite now familiar threats from Moscow: “I have a war in my country,” he said.

“They’re hitting my cities, my hospitals, my kindergartens, my schools. They killed a lot of civilians. They're an army of rapists, murderers and looters. What's the next level of escalation?"

You can read the full interview here.

The fighting in Ukraine has been relatively static in recent weeks, with neither the Russians or Ukrainians making major territorial gains in either the eastern or southern fronts over the winter.

Below are some maps illustrating the rough areas of control of either side, as of 11 January.

Since these maps were produced, Russia has claimed victory in the mining town of Soledar in eastern Ukraine - although Kyiv disputes this.

Energy Minister Herman Halushchenko has warned of "difficult days" ahead after Russian missile strikes damaged energy facilities in six Ukrainian regions.

In a Facebook post he wrote: "Today the enemy again attacked the country's generation facilities and electricity networks. There are hits in Kharkiv, Lviv, Ivano-Frankivsk, Zaporizhzhia, Vinnytsya and Kyiv regions.

"Emergency outages are being employed in most of the regions because of the strikes."

Halushchenko added energy specialists were already working to fix the damage, but he warned that the "coming days will be difficult".

Missile debris from a Russian strike on western Ukraine has been found in neighbouring Moldova, the country's interior ministry has said.

Police found the remnants of the strike in Larga, on the border with Ukraine in the north of the country, the ministry wrote on Facebook.

Moldova is a Romanian-speaking republic which borders the west of Ukraine, which itself has a breakaway province - Transnistria - in the west of the country that is economically, politically and militarily supported by Russia, which has an estimated 1,500 soldiers there.

The narrow strip of land between the Dniester river and the Ukrainian border, which broke away from Moldova in 1990, is not recognised by the majority of the international community.

At least five people have died after a Russian missile struck a residential building in Dnipro, the region's governer has said.

Valentyn Reznichenko wrote on Telegram that 27 people have been injured, including six children - all of whom are being treated in hospital.

Ukraine's foreign minister has urged the G7 and EU to sanction Russia's missile and drone industry.

Speaking in the aftermath of the latest wave of Russian missile strikes on Ukraine on Saturday, Dmytro Kuleba urged the two organisations to implement the relevant sanctions put forward by his country "without delay".

More now on the situation in Dnipro where a Russian missile hit a residential building earlier.

Kyrylo Tymoshenko, the deputy head of the Ukrainian presidential office, says 15 people have been rescued from the rubble of the nine-storey block of flats in the eastern city.

He adds that at least 10 people, including two children, were injured in the strike.

We are getting reports of what looks like a second wave of missile attacks across the country.

The mayor of Kyiv, Vitali Klitschko, has reported explosions in the city, adding that air defences were working.

And Ukrainian officials have also said that key infrastructure in the Kharkiv and Lviv regions in the east and the west have been hit.

A Russian missile has hit a residential building in the city of Dnipro and people are trapped under the rubble, a Ukrainian official has said.

Kyrylo Tymoshenko, the deputy head of the Ukrainian presidential office, posted a picture on Telegram of a block of flats that was badly damaged by an explosion.

He said that people who were at home for the St Basil's Day holiday in Ukranie were trapped under the rubble, adding that emergency services were at the scene.

As a result of the earlier missile strikes this morning, 11 regions of Ukraine are currently experiencing emergency power cuts to conserve energy.

The Ukaniant state energy company, Ukrenergo, wrote on Telegram that round-the-clock consumption limits have been set for all regions until midnight local time.

But the power firm said 11 regions had already exceeded this and are currently operating with emergency outages as exceeding the limit risks "causing emergencies in the energy system".

One of the earlier strikes from this morning hit a residential building in a village near Kyiv, leaving a massive crater in its wake.

Confirming the strike, Kyrylo Tymoshenko, deputy head of Ukraine's presidential office, said windows in some homes in the village of Kopyliv in Kyiv Region had been shattered by an explosion wave.

No casualties have been reported from the strike on the village, located about 50km (31 miles) from the capital.

Cities like Kyiv are sadly well-rehearsed in bracing for large-scale missile attacks. However, 2023 had been relatively quiet since the last strikes on New Year’s Day.

We headed to the shelter after explosions in took place earlier this morning. Worryingly, then the sirens didn’t sound for a couple of hours. Ukraine’s Air Force said it was because ballistic missiles had been launched from the north. They’re harder to detect because of the altitude and speed they fly at.

Heading to this underground car park is a lot easier than on 24 February last year. Back then, the people we were with were experiencing the trauma of their country coming under attack. Today, it’s mostly a bit annoying.

It’s a mixed picture as to what’s happened above ground. Authorities say infrastructure was hit in the east of the city, but we don’t yet know what.

Russian missiles have been reported seen flying over Ukraine, while air defence has downed at least one attempted barrage, the regional governor of the southern Mykolaiv region, Vitaliy Kim, has said.

Russia's warning that UK-supplied tanks for Ukraine are "legitimate military targets" is nothing new.

Since Western nations began supplying military aid, Moscow has warned repeatedly that US and Nato vehicles transporting weapons on Ukrainian territory will be considered targets for the Russian military.

The Russian Defence Ministry has also claimed on multiple occasions that "storage sites of Nato weaponry" have been destroyed by its forces, but there has been no confirmation of this.

Air raid sirens have been activated across much of Ukraine, officials have reported.

Earlier, the Ukrainian government said a second wave of missile strikes was incoming.

We will bring you more on this as soon as we have it.

The Challenger 2 is the British army's main battle tank. Here's a quick summary of its capabilities:

• It entered service in 1998, and is currently undergoing upgrades which will keep it in service until 2035
• It is currently in service with the Queen’s Royal Hussars, the King’s Royal Hussars and the Royal Tank Regiment
• It was most notable use was in the Iraq War
• The Challenger 2 has a crew of four, and carries a 120mm main gun and two 7.62mm machine guns
• Its top speed is around 59km/h (36mph)

Reporting from Moscow

In response to the announcement that the UK will provide Ukraine with Challenger 2 tanks, Russian Foreign Ministry spokeswoman Maria Zakharova told BBC News: "As we’ve said previously, weapons supplies are legitimate targets for Russian strikes."

The UK's opposition Labour Party have backed the government's decision to provide Ukraine with tanks.

But shadow defence secretary John Healey criticised the government for the way it has been handling the announcements of support for Ukraine.

He said ministers "must move beyond ad hoc announcements" and set out a plan for providing military, economic and diplomatic support this year and beyond.
