Ukraine's defence ministry said on Monday that an explosion in Dzhankoi in the north of the Crimean peninsula destroyed Russian cruise missiles intended for use by Russia's Black Sea fleet.
A Russia-installed official in the peninsula, which was annexed by Moscow in 2014, said the blast was caused by drones laced with shrapnel and explosives and targeted civilian sites. One person was injured.
A statement by the intelligence directorate of Ukraine's Defence Ministry said: "An explosion in Dzhankoi city in the north of temporarily occupied Crimea destroyed Russian Kalibr-KN cruise missiles as they were being transported by rail".
