While Jens Stoltenberg is giving his press conference, Nato has published the declaration, external issued by the heads of state at the meeting.

It says Nato will significantly increase deterrence and defence and will invite Sweden and Finland to join the alliance.

It says the commitment to Article Five - which states an attack on one Nato member is an attack on all - is "iron-clad".

It says Russia's attack on Ukraine "gravely undermines international security and stability" and Russia is the "most significant and direct threat to Allies’ security and to peace and stability in the Euro-Atlantic area" - and that Nato "will continue and further step up political and practical support" to Ukraine.

The leaders have endorsed a new Strategic Concept, external, which the declaration says reaffirms Nato's core values and spells out is key purpose.

Nato will strengthen its commitments to Ukraine, Stoltenberg said, and the country can rely on Nato's "continued support".

"Ukraine can count on us for as long as it takes," he said.

He added this "unshakeable" commitment would see more military and financial help.

This includes giving Ukraine access to "modern Nato equipment," he said.

Stolenberg added this would strengthen Ukraine's defence and security.

Jens Stoltenberg says Russia's President Putin has "shattered peace" in Europe and that this is the biggest security crisis since World War Two - reiterating earlier comments.

He said Ukraine's President Zelensky spoke to Nato leaders today and described his leadership and courage as an "inspiration".

Stoltenberg said leaders assured Ukraine that it can continue to count on their support for as long as it takes, and allies will provide military and financial help.

Nato member states agreed to strengthen support for Ukraine by pledging a "comprehensive assistance package", he added.

He also said a strong independent Ukraine is "vital" for stability in Europe.

Jens Stoltenberg, who's Nato's secretary-general, has just started speaking at the summit in Madrid. We'll bring you full details of what he has to say.

Millions of people across the globe may face hunger due to Russia's "dirty games" of blocking Ukrainian food exports, a spokesman for the Ukrainian Foreign Ministry has claimed.

Oleh Nikolenko tweeted his comments after Russian Foreign Ministry press secretary Maria Zakharova's remark that Russia is ready to export dozens of millions of tonnes of grain "if the West stops blocking food supplies".

Nikolenko responded that Russia "never run out of excuses".

"Russia's blockade of Ukraine's sea ports undermines global food security," he says.

"If Ukrainian grains are not freed, the world will face famine.

"Millions of people became hostages of Moscow's dirty games."

Meanwhile Turkey says it will now be pushing for the extradition of 33 "terror" suspects from Finland and Sweden, under that deal that lifted Ankara's objections to the two Nordic states' bids to join Nato.

Turkey would ask them to "fulfil their promises", its justice minister said.

Ankara has accused both Finland and Sweden of hosting Kurdish militants.

The Nordic states agreed late on Tuesday to "address Turkey's pending deportation or extradition requests of terror suspects expeditiously".

After four hours of talks at the Nato summit in Madrid the three countries reached a compromise and Finland and Sweden are to be invited formally to join.

Russia, for its part, condemned the expansion of Nato as a "strictly destabilising factor".

Fresh-faced and smiling in Madrid, PM Magdalena Andersson looked happy as she told Swedish Television’s morning show that she’d slept well after the “big day” that saw Turkey finally agree to a Nato spot for Sweden and Finland.

It was a marked contrast to the reaction from Amineh Kakabaveh, an independent MP and a member of Sweden's 100,000-strong Kurdish diaspora. She's appeared on international TV channels to argue Sweden shouldn’t make concessions to Turkey, which she describes as an Islamist dictatorship.

Speaking on a crackly line from the passenger seat of a moving car, Kakabaveh described Tuesday as “a black day in Swedish political history” and said Kurds were being sacrificed for the sake of Nato membership.

But while plenty of Kurds in Sweden back Kakabaveh, she has little power. Around 80% of MPs supported Sweden's Nato application, and with parliament now broken up and an election due in September, Andersson’s Social Democrat party no longer needs Kakabaveh's support.

A little earlier we said that we would be hearing from Nato's secretary general Jens Stoltenberg (pictured above between Joe Biden and Boris Johnson) around now.

We now think he'll be speaking in about half an hour - we'll bring you full details of what he says when we have them.

At 14:00 BST the heads of state and government of Nato countries will be meeting as part of the North Atlantic Council.

After that we expect to hear from Stoltenberg again, before the leaders gather for a dinner at Madrid's Prado museum.

More from Madrid now, where Ukrainian President Volodymyr Zelensky told leaders his country needs more modern weapons and financial support to defend itself against Russia,

The leader - addressing the likes of US President Joe Biden and French President Emmanuel Macron via video link - also warned that Russia wouldn't stop at Ukraine.

The question is, "who is next?", he asked adding,:

Pope Francis has condemned Monday's bombing of a crowded shopping centre in Kremenchuk as the latest in a string of "barbarous attacks" against Ukraine.

The missile strike by Russian forces killed 20 people, with dozens wounded.

The Pope told crowds gathered at St Peter's Basilica in Rome that he prayed "this mad war can end soon".

He added Ukraine had been "martyred" by Russia's unprovoked attack.

Oligarch Vladimir Potanin – Russia's second richest man and a member of Putin’s inner circle – is among the latest people to be sanctioned by the UK over his country's invasion of Ukraine.

Since the war started, Potanin has continued to grow his wealth by acquiring Rosbank and shares in Tinkoff Bank, the UK government said. He's estimated to be worth £13bn.

He's now subject to a travel ban and had his assets in the UK frozen.

Vladimir Putin's cousin Anna Tsivileva, who is president of a mining company, is also sanctioned.

The UK said today’s new sanctions will “weaken the Russian war machine”.

“Nothing and no one is off the table,” said a spokesperson.

US President Joe Biden, British PM Boris Johnson and French President Emmanuel Macron are among the Nato heads of states and governments who posed for a group photograph - often dubbed the family photo - as today's events got under way in Madrid.

Not yet in the family, or the photo, are the leaders of Sweden and Finland. Both are in Madrid for the summit, however.

Later today we should see the leaders gather for the formal meeting of the North Atlantic Council. Before that we expect to hear from Nato's secretary general, who is due to speak to reporters within the next hour or so.

You may have seen that Boris Johnson has said that Russian President Vladimir Putin would not have invaded Ukraine if he were a woman.

The UK prime minister said the "crazy, macho" invasion was a "perfect example of toxic masculinity" and he called for "more women in positions of power".

But Downing Street said there was "not a deliberate policy" to publicly belittle Putin.

"The British public would expect leaders to be robust with someone killing innocent civilians on a daily basis”, says a spokesman for Boris Johnson.

You can see Johnson talking about the importance of having women in positions of power in this clip from his interview with German broadcaster ZDF:

A lasting peace in Ukraine will only be possible if three conditions are met, the Foreign Secretary Liz Truss tells the BBC on the sidelines of the Nato summit in Madrid.

Firstly, she said, Russia needed to be pushed out of Ukraine.

Secondly, Russia needed to be held to account for its alleged war crimes.

And thirdly, there needed to be certainty that future Russian aggression can be prevented so there could never be a repeat of the Ukraine invasion.

There is a renewed sense of purpose and determination here at this Nato summit, with all 30 members signing up to a revised strategy that aims to deter President Putin from attacking any other countries, especially those on Nato’s eastern flank who feel most at risk.

But allocating more military resources to shoring up Nato’s defences is going to stretch both budgets and manpower.

There are also private differences between those nations, like Britain which is urging the alliance to keep sustaining Ukraine’s war effort for however long it takes, and others which fear the economic costs may eventually prove too high to bear.

If you're just joining us, here's a summary of the main developments so far on another busy day of Ukraine news:

• Nato leaders have gathered again in Madrid for a summit, and of course the war in Ukraine is dominating discussions
• Sweden and Finland are on track to join the defence alliance after member Turkey withdrew its objections, with Russia reportedly calling the plans "destabilising"
• Meanwhile, US President Joe Biden has announced the expansion of American forces in Europe after Russian President Putin "shattered peace" by invading Ukraine
• Speaking from the summit, UK PM Boris Johnson described the invasion as "crazy", "macho", and something that wouldn't have happened if Putin was a woman
• On the ground in Ukraine, three people are reported to have died after eight missile strikes hit the southern city of Mykolaiv
• Meanwhile he country's President Zelensky released CCTV footage showing the moment on Monday that a missile struck a shopping centre in Kremenchuk, killing 20 and wounding dozens

Russia views plans by Sweden and Finland to join Nato "negatively", according to comments from the country's Deputy Foreign Minister reported by Interfax.

Sergei Ryabkov is also quoted by Russian state news agency RIA as saying that the expansion of Nato is "destabilising" and does not add to the security of members of the alliance.

Sweden and Finland will be formally invited to join Nato, according to Secretary-General Jens Stoltenberg, after Turkey dropped its objections.

He said the expansion of Nato was "the opposite" of what President Vladimir Putin hoped for and instead showed that the alliance's "door is open".

They are dramatic and seem conclusive. CCTV images dated just before 16:00 local time (14:00 BST) on 27 June show something slamming into a building, sending a huge cloud of fire and debris into the air.

Slowed down it is clearly a missile.

There are a number of details – a tower, a railway crane – that have allowed investigators to pinpoint the location of the strike. It was the shopping centre in Kremenchuk.

It follows a concerted attempt by the Russians to present often contradictory theories: saying it was a hoax, it was carried out by Ukraine or it was a secondary blast that destroyed the AMStore complex.

In his nightly address, President Zelensky called out “those Russian propagandists who lie about this terror” saying they too would be punished.

We reported a little earlier that Ukraine's President Zelensky released CCTV footage last night showing the moment a missile struck a shopping centre in Kremenchuk on Monday

The death toll from the strike has risen to 20 while dozens of people have been injured.

Back now to the situation on the ground in Ukraine, and at least three people are reported to have died after a Russian missile strike hit a residential building in the southern city of Mykolaiv.

Local authorities say five people have also been injured in the strike and a rescue effort for survivors has been launched.

Mayor Oleksandr Senkevych says eight missiles hit the city and has urged residents to evacuate.

Photos from the scene showed smoke billowing from a four-storey building with its upper floor partly destroyed.

Mykolaiv, located 100km (62 miles) north-west of Kherson, has been a key target for Russian forces since the invasion began.

US President Joe Biden has announced an expanded military presence of American forces across Europe in response to Russia's invasion of Ukraine.

Speaking at the Nato summit in Madrid earlier, he said US forces would be strengthened across land, air and sea, as Russian President Vladamir Putin had "shattered peace".

Biden, who was meeting with Nato chief Jens Stoltenberg, said: "Together with our allies we're going to make sure that Nato is ready to meet the threats from all directions across every domain."

Nato is as "important as it ever has been", he said, adding that Finland and Sweden's applications to join the alliance were "exactly what he [Putin] didn't want".

It comes as the two Nordic countries are on track to end their historic neutrality and join Nato after alliance member Turkey withdrew its objections last night.
