Some more now from NATO Secretary General Jens Stoltenberg's joint press conference with Ukrainian President Volodymyr Zelensky.

Stoltenberg said "the biggest risk" would be if Russian President Vladimir Putin won the war in Ukraine, in strong remarks highlighting the threat of the conflict to Europe's security landscape.

“There is a full-fledged war going on in Europe and there is no risk free option for NATO allies, but the biggest risk is if President Putin wins,” Stoltenberg said on the second day of the NATO summit in Vilnius in Lithuania.

“That’s exactly why it's important for NATO allies to support Ukraine," he added.

"It will be a tragedy for Ukraine if President Putin wins, but it will be dangerous for us, it will make us more vulnerable.” he added.
