UK PM Rishi Sunak and US President Joe Biden have held a bilateral meeting in Bali in an open-air room surrounded by a carp pond and tropical plants.

"At the moment where world leaders meeting here in Bali are seeking progress on world peace, Putin’s striking civilian targets - children, and women. I mean, it’s just, it’s almost - in my words, not yours - barbaric,” said Biden.

Sunak said he agreed Russian missile attacks were barbaric.

The pair declined to take questions from reporters on the explosion in Poland - but Biden earlier said it seemed unlikely that the missile was fired from Russia.
