Sept. 12 (UPI) -- Russia said Friday that it shot down hundreds of Ukrainian drones overnight, many of them targeting facilities of the multinational Russian oil company, Lukoil, southwest of Moscow, according to the defense ministry.

More than half of the 221 UAVs were brought down over the regions of Smolensk and Bryansk, where five civilians and two military personnel were injured after a bus was struck, while nine got through to the Moscow area before being destroyed.

Moscow Mayor Sergey Sobyanin said emergency services were attending a location hit by falling debris from downed drones but gave no details of where or the extent of the damage. Russian social media accounts reported blasts in Mozhaysk and Dedovsk in the western suburbs of the capital.

As many as 30 others were intercepted in the Leningrad region, temporarily closing St. Petersburg's Pulkovo airport and setting ablaze a vessel at Russia's largest oil terminal northwest of the city at Primorsk on the Baltic Sea.
