Authorities in Russia's second city of St Petersburg and the surrounding Leningrad region said on Saturday the area suffered a major Ukrainian drone attack overnight, with a Baltic Sea port that handles oil exports reported hit.
St Petersburg Governor Alexander Beglov said the city of 6 million had come under a "large-scale" drone attack. He gave no details of specific targets, but local media outlet Bumaga reported a fire at the city's oil terminal.
Leningrad region Governor Alexander Drozdenko said drones had struck the port of Vysotsk, about 170 km (105 miles) northwest of St Petersburg on the Gulf of Finland. The port handles oil, grain, coal and liquefied natural gas.
