A high-profile Ukrainian combat brigade has allegedly captured dozens of Russian soldiers amid fighting in the Kharkiv region.

Footage shared by Ukraine's 3rd Assault Brigade appeared to show the soldiers sitting in a school conference room.

The Ukrainian brigade said the troops were taken prisoner during combat operations around the northern Ukrainian town of Vovchansk.

Social media figures had previously reported substantial numbers of Russian troops surrendering in the area last week after counterattacks by Ukrainian infantry assault units.

The Khortit*iya Regional Command also claimed more than 60 Russian soldiers had been captured in the area in less than a week.

The Euros begin tomorrow, and for most teams the tournament is the first thing on their mind.

But for Ukraine's national team, they are also focused on their country's fight for freedom.

Thirteen players from the team have taken part in a video calling for the world to support Ukraine.

As each state where they were from, images of destruction in each city flash up.

"Our hometowns would like to host the Euros, but now they are fighting not for the tournament but for freedom," the video says.

The Russian advance on Kharkiv came at a "high price" for its troops, a NATO official has told European Pravda.

The official, who spoke on condition of anonymity, said: "Russia likely suffered losses of almost 1,000 people a day in May, which is quite an astronomical figure."

They were referring specifically to fatalities.

Russian forces have advanced less than 10km into Ukrainian territory and have not taken control of the city of Vovchansk.

The US defence secretary earlier said Russia's advance was slowing and the frontline stabilising, partly thanks to countries lifting restrictions on Ukraine's use of donated weapons on Russian territory.

The US president will skip the planned G7 dinner tonight, diplomatic sources have told our international affairs editor Dominic Waghorn.

The official dinner is being held by Italian President Sergio Mattarella in the Swabian Castle of Brindisi.

Joe Biden is skipping due to "a busy schedule and tiredness", according to Italian news outlet la Repubblica.

He will return to the US tomorrow for an event in Los Angeles.

Volodymyr Zelenskyy and Joe Biden are now addressing the issue of Chinese and Russian cooperation.

The US earlier expanded sanctions against companies and individuals accused of helping Russia's war effort, including entities in China.

Beijing has repeatedly denied it is supplying Russia with weapons, however it has been accused of providing critical components for Russia's war.

Mr Zelenskyy says he was told by President Xi Jinping that China would not sell weapons to Russia.

It's not clear when this conversation took place.

Meanwhile, Mr Biden says China is helping Russia in the war through technology and production.

Volodymyr Zelenskyy acknowledges the impact of the months-long delay to US weapons support, which was caused by Republicans blocking a major aid bill.

He says the pause in supplies had allowed Russia to conduct an offensive on the northeastern region of Kharkiv, but Ukraine had managed to stop it.

Meanwhile, Joe Biden made clear the US had not changed its position on allowing Ukraine to use American weapons to strike inside Russia.

The US recently said it would allow Kyiv to use such weapons to strike Russia only for the purpose of stopping the attack on Kharkiv.

We're hearing now from Joe Biden and Volodymyr Zelenskyy, who are holding a joint news conference after it was revealed the US and Ukraine have signed a major 10-year security agreement.

The US president repeats his message that he will "stand with Ukraine" and says it is a "reminder to Putin that we are not backing down".

Mr Biden says lasting peace for Ukraine must be underwritten by Ukraine's ability to defend itself.

The agreement includes major commitments from Ukraine to implement reforms required by both the EU and NATO in order for Kyiv to join.

Steps taken by the G7 today will help Ukraine to succeed in its war against Russia, Mr Biden says, and leaders also discussed concerns about China supplying Moscow with "materials for its war machine".

Mr Zelenskyy says today is a "truly historic day" and that the security deal is the strongest agreement since Ukraine's independence.

He thanks Mr Biden for his leadership and says the deal will create jobs in both the US and Ukraine.

A Russian journalist covering the war has been killed by Ukrainian shelling on a village in eastern Ukraine, according to a local mayor.

Valery Kozhin, who worked for Russia's NTV television channel, was reportedly among a group of journalists hit in the strike on Holmivskyi.

NTV earlier reported three of its staff, including Mr Kozhin, had been injured and taken to hospital.

Holmivskyi is in the Donetsk region of Ukraine.

The $50bn support package agreed by G7 leaders today is "game-changing", Rishi Sunak has said.

The UK prime minister said it would support Ukraine on the battlefield and in its economic reconstruction - but would also send a "signal" to Vladimir Putin.

"The signal that will send, the deterrence, is as important as the actual practical support and that has been what we've been focused on," he said.

Mr Sunak said the money would be provided by the G7 as a loan and then secured against profits of seized Russian assets.
