Ukrainian drones hit St Petersburg as ‘Russian Davos’ opens in city

Energy and military sites targeted as guests gather for economic forum where Putin is due to speak on Friday

Ukrainian drones hit energy and military sites in St Petersburg early on Wednesday hours before international guests gathered for the city’s flagship economic forum, in a blow to Vladimir Putin.

Several long-range drones crashed into oil storage facilities after Russian air defences tried unsuccessfully to shoot them down. There were loud explosions and black smoke rose high above the city from the blazing oil terminal.
