An aircraft maintenance plant close to Lviv has been hit with missiles, the city's mayor says.

It is the closest the war has come to the historic city in western Ukraine, which has been a safe haven for people fleeing fighting.

The mayor says no casualties have been reported so far and rescue workers are at the site.

Two million people have fled Ukraine to Poland since the war began, the Polish Border Guard agency says.

Ukrainian counterattacks and logistical woes are stalling Russia's offensive in Ukraine, according to a UK military assessment.

US President Joe Biden will urge China not to provide Russia with military equipment in a call with President Xi Jinping later.

Survivors are reported to be emerging from the ruins of a theatre in Mariupol that Ukrainian authorities say was bombed by Russia.
