Move comes after assault by airborne and underwater drones in which flagship may be been damaged
Russia has said it will pull out of a UN-brokered grain export deal after a dramatic attack by Ukrainian airborne and underwater drones on its Black Sea naval base of Sevastopol in the early hours of Saturday morning.
Social media showed footage of explosions both near and in the Crimean harbour, and Russia’s defence ministry said there had been an attack by “nine unmanned aerial vehicles and seven autonomous sea drones” that began at 4.20am.
