Air raid sirens have gone off again in Kyiv and across Ukraine. The threat of further bombardment comes just a day after Russia launched some of the worst attacks on the Ukrainian capital and other cities not near the front in months.

The southern Ukrainian city of Zaporizhzhia has been targeted with further missiles overnight, the regional governor has posted on the Telegram messaging app.

Oleksandr Starukh wrote just after 06:00 local time that Russia had struck infrastructure - adding that information about damage and casualties was still being ascertained.
