Russian officials reportedly shot roughly 30 drones at Kyiv early on Sunday, causing explosions to resound across the Ukrainian capital and the surrounding area for two hours and the fall of debris across multiple city districts, according to Ukrainian officials.

According to Ukraine’s air force, 26 of the 33 Russian drones that were launched and targeted Kiev and the surrounding area were destroyed.

Reuters witnesses heard at least five explosions across Kyiv, where the nighttime sky was illuminated by blasts from air defences engaging the targets. A plume of smoke roese from in between buildings.

Kyiv resident Liudmyla said she heard the buzzing of the Iranian-made drones before a blast wave shattered windows in her building and the jars on her windowsill. “It was a very frightening experience – I can’t even put it into words.”

Fragments from downed drones fell on five different districts, said Mayor Vitali Klitschko and the city’s military administration. Klitschko said one person had been injured.

The state emergency service later reported that debris had fallen in three districts but that there was no serious damage.

Kyiv region Governor Ruslan Kravchenko wrote on Facebook that an unspecified infrastructure facility and eight houses had been damaged as a result of the overnight strikes.

There was no immediate comment from Russia about the attacks. Moscow has conducted regular air strikes on Ukrainian population centres far from the eastern and southern front lines of its 18-month-old invasion.

A Russian attack killed 17 people on Wednesday in the eastern city of Kostiantynivka, Ukrainian officials said.
