At least five people, including a one-year-old child, were killed in a Russian drone strike on the northern Ukrainian city of Pryluky overnight, regional governor Viacheslav Chaus said today.

The attack came just hours after Donald Trump spoke with Russian President Vladimir Putin.

According to Trump, Putin “very strongly” said that Russia will retaliate for Ukraine’s weekend drone attacks on Russian military airfields.

Six more people were wounded in the attack and have been hospitalised, Chaus said.

According to him, six Shahed-type drones struck residential areas of Pryluky early this morning, causing severe damage to residential buildings.

Hours later, seventeen people were wounded in a Russian drone strike on the eastern Ukrainian city of Kharkiv early today, including children, a pregnant woman, and a 93-year-old woman, regional head Oleh Syniehubov wrote on Telegram.

About 1.05am local time, Shahed-type drones struck two apartment buildings in the city’s Slobidskyi district, causing fires and destroying several private vehicles.

“By launching attacks while people sleep in their homes, the enemy once again confirms its tactic of insidious terror,” Syniehubov wrote on Telegram.
