Russia will summon Britain's ambassador to Moscow over what it said was the involvement of British specialists in a Ukrainian drone strike on its Black Sea Fleet in Crimea, the foreign ministry said on Wednesday.
Russia suspended participation in a U.N.-brokered Black Sea Grain Initiative on Saturday after what it said was a major drone attack on vessels in the Bay of Sevastopol on the Crimean peninsula, which Russia annexed from Ukraine in 2014.
