At least 11 civilians have been killed in Russian shelling on Ukraine’s former capital and second most populated city, Kharkiv, on Monday, the regional governor said, adding dozens more had been injured.

“The Russian enemy is bombing residential areas,” Oleg Sinegubov, wrote on the Telegram messaging app, saying that: “As a result of the bombardments that are ongoing, we cannot call on the emergency services… currently there are 11 dead and dozens wounded”.

The United States also recommended Monday that Americans in Russia leave immediately following the invasion of Ukraine.
