Russian forces launched a massive nighttime aerial assault on Ukraine’s Rivne Oblast early on 9 June, injuring one civilian, according to regional military administration head Oleksandr Koval.

Rivne Mayor Oleksandr Tretyak said that it was the most extensive assault on the oblast to date. Russian forces deployed dozens of Shahed drones and missiles against the oblast, Tretyak said.

Air defense forces destroyed numerous targets during the bombardment, Koval said. Defense forces and emergency services personnel are working at the strike sites, though the regional administration chief did not specify additional consequences of the Russian attack.

Explosions were heard overnight in Rivne, Dubno, and other settlements across the oblast. Ukraine’s Air Force had warned of missiles and drones heading toward Rivne and Dubno.

The assault extended beyond Rivne Oblast as Russian troops attacked Ukraine with Shahed drones from multiple directions while launching cruise and ballistic missiles. Kiev experienced explosions, with one drone striking an office building in the Darnytskyi district, according to the Kyiv City Military Administration head Tymur Tkachenko.

The attack also affected Kyiv Oblast’s Boryspil district, where a residential building, outbuilding, and vehicle sustained damage, Kyiv Oblast police reported on Telegram.

The attack damaged a private house, car, and farm building in Boryspil district. No casualties has been reported.

Patrol officers, an investigative team, and explosives experts are working at the scene in Boryspil district. The air raid alert lasted over six hours as air defense systems operated across Kyiv and the surrounding oblast.

The overnight assault represented Russia’s latest large-scale drone attack on Ukraine, with explosions reported in multiple cities across the country.
