Russia has struck an American-owned factory with cruise missiles overnight in one of the largest aerial attacks since the war began.

The Ukrainian air forces said some 574 drones and 40 missiles were fired overnight.

The strikes killed one person and injured 15 more, striking a "major American electronics manufacturer", according to Andrii Sybiha, Ukraine's foreign minister.

Far from the battlefield's front line in the east and south of Ukraine, the strikes focused on western regions.

It comes days after Russian President Vladimir Putin travelled to Alaska to meet US President Donald Trump to lay out his terms for peace.

This includes Ukraine withdrawing from the entire Donetsk region, despite it not currently being under Russian military control.

Ukrainian President Volodymyr Zelensky said the attack was carried out "as if nothing were changing at all".
