Turkish President Tayyip Erdogan said all of Turkey's sensitivities have been included in accord with Finland and Sweden.

He said the two countries must meet their promises on Kurdish groups, including changing laws, before he sends ratification of their Nato bid to parliament.

Earlier on, Nato's Secretary General Jens Stoltenberg said Finland and Sweden will sign their accession protocols to join the military alliance on Tuesday.

But Erdogan said the two countries must fulfil promises they made to Turkey in a deal to lift its veto on their Nato membership bids.

Erdogan said Stockholm pledged to extradite 73 "terrorists".

He said the signing of the trilateral accord was a recognition of Ankara's sensitivities around terrorism and a "diplomatic victory" for Turkey.

During a news conference, he said efforts must be intensified for a lasting ceasefire in Ukraine.

Vladimir Putin has hit back at Western leaders who mocked his macho image this week, saying it would be "disgusting" to see them strip off.

It comes after leaders at the G7 summit poked fun at the Russian president's tendency to pose for topless photos.

But Putin suggested his counterparts needed to cut out alcohol and do more sport.

Putin has been pictured shirtless several times in Russian state media, including whilst riding a horse, carrying a hunting rifle, and going fishing.

The pictures have been widely interpreted as the Russian president seeking to project a sense of masculinity that appeals to many Russians.

At the G7 summit in Germany earlier this week, UK Prime Minister Boris Johnson took a swipe at him, joking the leaders should take their clothes off to "show that we're tougher than Putin".

Snake Island (or Zmiinyi as it is known locally) may be a tiny dot in the Black Sea, but Russia's failure to hold on to it is far more than symbolic.

The fact the Russians were unable to remain there represents a highly significant defeat for the invading forces.

Moscow's claim that this is a goodwill gesture lacks any kind of plausibility and is more likely an attempt to save face. The defence ministry claims this is all about showing the world that it is not impeding Ukrainian grain exports. As the BBC has highlighted, Russia has devoted considerable resources to expropriating Ukrainian grain.

A more likely explanation is that Snake Island has proved very hard to defend. Every time Russia tried to beef up its defences in recent months, the Ukrainians launched an attack. The latest operation involved several explosions. Kyiv would also struggle to defend it, but they might not need to.

The fact that Russian forces no longer have a base in the far north-west corner of the Black Sea is a dramatic victory for Ukraine. But Kyiv is still a long way from being able to send its grain ships out of Odesa.

Why Russia couldn't hold on to Snake Island.

Russia’s nuclear rhetoric is "reckless and dangerous," according to Nato secretary general Jens Stoltenberg.

Speaking to me at the Nato summit in Madrid, he said the Western alliance had to take it seriously but has not seen any changes in Russia’s nuclear readiness.

He also said that China should stop threatening Taiwan and not create a dangerous situation in that part of the world because what happens there also matters to Nato.

But Stoltenberg refused to be drawn on whether the alliance would come to Taiwan’s aid if it was attacked.

On Russian indignation at Finland and Sweden joining Nato, he said those countries had the right to choose their own path.

He also totally rejected the idea that Nato is partly responsible for the Ukraine war, saying that Russian President Vladimir Putin doesn’t like having a free, democratic, successful nation on his borders.

Stoltenberg also praised the UK for providing high-end capabilities to Nato and being a key supporter of Ukraine.

Nato allies, he said, are prepared to continue supporting Ukraine for as long as it takes because this is also about ensuring President Putin doesn’t get his way by using force against a sovereign nation in Europe.

If you're just joining us or need a re-cap, here are the latest headlines:

• Russia's forces have left the strategic outcrop Snake Island in the north-western Black Sea, which has been fought over since the start of the war
• Ukraine sees the retreat as a victory, while Russia said giving up the island was a "goodwill gesture"
• Sanctions against Russia could be seen as acts of aggression and a justification for war, according to Dmitry Medvedev, Russia's deputy security council chairman
• Sweden and Finland will sign the protocol to join Nato on Tuesday, the head of the alliance said, though member states will still need to ratify it
• US President Joe Biden has said he will announce a further $800m (£658m) of military aid for Ukraine in the coming days
• UK Prime Minister Boris Johnson has pledged to increase defence spending to 2.5% of GDP by the end of the decade to adapt to a "more dangerous" world
• Russia continues its assault in the eastern Donbas region, as the regional governor of Luhansk says the city of Lysychansk is under "enormous" amounts of shelling

"We will defend every inch of Nato territory," Biden told the conference in Madrid.

He added the US was "rallying the world" to stand with Ukraine.

More than 50 countries had pledged new commitments, he said.

This includes:

• More than 600 tanks
• Nearly 500 artillery systems
• More than 600,000 rounds of artillery ammunition
• Advanced multiple launch rocket systems, anti-ship systems and air defence systems

US President Joe Biden says he'll be announcing a further $800m (£658m) worth of military aid for Ukraine in the coming days.

He suggests it will cover air defence, artillery, counter-battery systems and other weaponry.

It's the latest in a series of announcements of support the US has given Ukraine since Russians' invasion began. The US has sent more than $50bn of aid to Ukraine so far.

We've just heard US President Joe Biden recall how he warned his Russian counterpart Vladimir Putin before the war that "if he invaded Ukraine, Nato would not only get stronger, but would get more united".

He said he had told the Russian leader that democracies across the world would "stand up and oppose his aggression".

"And that's exactly what we are seeing today," added Mr Biden.

The president told Nato's Madrid summit that supporting Ukraine was protecting the "rules-based order".

"We're going to support Ukraine for as long as it takes," US President Joe Biden says in his news conference at the Madrid Nato summmit.

Biden points out the impact the war has had on Russia already, having had to renege on national debt, losing 15 years of gains in their economy, having trouble maintaining oil production and weapons systems because of technology no longer being available to Moscow because of sanctions.

"They're paying a heavy heavy price for this - just today Snake Island is now taken over by the Ukrainians.

"We are going to stick with Ukraine and all of the alliance is going to stick with Ukraine as long as it takes, to in fact make sure they are not defeated by Russia.

"Ukraine has already dealt a severe blow to Russia - Russia has already lost its international standing, Russia is in a position where the whole world is looking and saying 'all this effort, you tried to take the whole country, you tried to take Kyiv and you lost, you tried to take the Donbas and you haven't done that yet'."

He says Ukraine's "overwhelming courage" is being supplemented by international support.

"I don't know how it's going to end but it will not end with a Russian defeat of Ukraine in Ukraine."

British Prime Minister Boris Johnson says the UK will increase its defence spending to 2.5% of GDP by the end of the decade.

The announcement comes as Nato leaders devise a new strategy to counter the threat of Russian aggression.

Johnson's pledge came despite disagreements within his government over defence spending, with the PM insisting the "cost of freedom" is "always worth paying".

A source close to Defence Secretary Ben Wallace said he was "very grateful".

The UK's pledge of an additional £1bn in military aid to Ukraine is "substantial but not enough", Dr Aglaya Snetkov, lecturer in International Politics at University College London, tells the BBC.

She says funding will have to keep coming given that Nato, the US and Britain have conceded the war may continue for a long time.

The new funding will demonstrate to Ukrainian citizens and soldiers on the ground "Zelensky's ability to keep the West interested" in terms of support for the war effort, Dr Snetkov says.

While Ukraine continues to request more financial aid, Dr Snetkov says Western military contributions so far have been "critical to Ukraine's effort".

"Without support from the West and Nato, the Ukrainian army simply would not be able to perform as they do - they have completely outperformed people's expectations and have been excellent on the ground," she adds.

Is the UK's £1bn ($1.2bn) pledge enough, given that President Zelensky says the monthly cost of defence for Ukraine is about $5bn (£4.12bn)?

"The reality is these [pledges] will have to keep on coming - war is very expensive and Ukraine is using up the military assistance on a daily basis," Dr Snetkov says.

"The question is now, what will be given and how quickly? We don’t actually know at this stage what the funding will look like in practice or when it is coming, which is critical - will it be weeks or months?", she adds.

We’ve grown accustomed to this: Russia putting out a version of events that is wildly different from that presented by Ukraine or by Western governments.

Moscow wants us to believe that there was no Russian retreat from Snake Island.

The statement issued by the Russian Defence Ministry claims that Russian troops there had simply completed “assigned tasks” and left.

It also called the departure “a goodwill gesture”, to show that Russia wasn’t hampering food exports from Ukraine.

Considering the strategic importance of Snake Island, which has been fought over for months, and considering, too, the lack of "goodwill gestures" by the Russian armed forces in Ukraine since the invasion, this version of events will convince few outside Russia.

Then again, this may be directed more at a domestic audience. The Kremlin wants the Russian public to believe two things - that in this conflict the Russians are the good guys and that Kremlin’s so-called "Special Military Operation" in Ukraine is going according to plan.

Sanctions against Russia could be seen as acts of aggression and a justification for war, according to Dmitiry Medvedev, Russia's deputy security council chairman.

"Under certain circumstances such hostile measures can also qualify as an act of international aggression," says Medvedev, a former Russian president, who called sanctions a "boorish and cynical practice".

Western countries have targeted wealthy individuals, banks, businesses and state-owned enterprises with sanctions since the invasion of Ukraine began in February.

Earlier this month Vladimir Putin called the sanctions "mad and thoughtless" and an "economic blitzkrieg against Russia" that had no chance of succeeding and that would be more harmful to those imposing them.

Nato's Madrid summit has come to a close and world leaders who are part of the military alliance have been sharing their reactions.

We've just been hearing from Nato Secretary General Jens Stoltenberg and British Prime Minister Boris Johnson.

French President Emmanuel Macron has said support for Ukraine cannot stop. "Ukraine's fight is the European Union and Nato's fight", he added.

Meanwhile, German Chancellor Olaf Scholz said he did not want to speculate how long Ukraine would need support for.

He called Putin's comments about Nato's imperialism "ridiculous", adding that no one can say what would make the Russian president end the war in Ukraine.

We've just heard UK Prime Minister Boris Johnson defend the "robust health" of Nato during his conference speech in Madrid.

He repeated what he has said previously about Russia's invasion bringing Nato closer to its doorstep, adding Putin's actions had made the alliance "stronger" and united the West.

On Putin's allegations about Nato being a threat to Russia, Johnson said it was "never remotely likely that Ukraine would join Nato in the foreseeable future" before the war.

It is up to the Ukrainian people to decide if and when they want to strike a deal with Russia to get peace, Boris Johnson says.

Asked by the BBC's Political Editor Chris Mason what the UK's objective for the conflict in Ukraine is, he says it is up to President Volodymyr Zelensky and the Ukrainian people to decide.

"We can't be more Ukrainian than the Ukrainians, everybody understands that," he says.

But he says he has seen that in a poll after the attack on the shopping centre in Kremenchuk, "89% of Ukrainians would under no circumstances contemplate a land for peace deal," and they did not want any sort of deal with Russia.

"Our job is simply to vindicate the principle, to stand up for the right of the Ukrainians to protect themselves, that's what we're doing."

He says the Western allies want to give Ukrainians the means to expel the Russians from their territory and put Zelensky in the best possible position if he decides he does want to talk to Russia about a deal. But Johnson points out Russian leader Vladimir Putin is not offering a deal.

Russia's decision to abandon the strategic Black Sea outpost of Snake Island was evidence of Ukraine's ability to fight back, Boris Johnson says.

"If you wanted evidence of the amazing ability of the Ukrainians to fight back to overcome adversity and to repel the Russians then look at what has happened just today on Snake Island, where again Russia has had to cede ground," Johnson told a news conference at the Nato summit in Madrid.

"In the end it will prove impossible for Putin to hold down a country that will not accept his rule."

Ukraine should not be forced into a "bad peace," UK Prime Minister Boris Johnson says.

He referred to Nato as "a purely defensive alliance”.

Johnson added that the fact that Finland and Sweden – which he called “peace-loving countries that have been neutral for decades” – were now joining Nato was “all you need to know” about Nato and Putin.

He added that if Ukraine was to concede to Russia's demands, the consequences around the world would be “appalling”.

"The Nato alliance is plainly in robust health and getting stronger, with new members and a renewed purpose," Boris Johnson says.

Our work is cut out, he says, and there are people around the world who need to understand our arguments.

He says Nato member countries have a huge advantage in being united, knowing what they want to do and having the means to do it.

Nato is more resolved than ever to support Ukraine, UK Prime Minister Boris Johnson says.

Virtually everyone around the table at the Nato summit has agreed to provide more assistance to Ukraine, he says.

The countries of Nato, the G7 and the Commonwealth will work together to help the world cope with the impacts of war, such as a rise in fuel prices and cost of living and shortages of food, he adds.

Not every country takes the same view of Russia's invasion, so some myths about the invasion need to be exploded, he says, such as that Nato provoked the conflict, or that Russia wasn't responsible for the blockage of grain exports, or that the West does not have the staying power to support those in need in Ukraine because of its own pressures.
