Russia's Defence Ministry said on Tuesday that a military warehouse near the town of Dzhankoi in northern Crimea had been damaged by sabotage, Russian state-owned news agency RIA reported.

Earlier on Tuesday, Crimean officials said there had been a major fire at an ammunition depot in the area. State-owned news agency TASS cited the Defence Ministry as saying that civilian infrastructure, including an electricity supply station had been damaged as a result of the "sabotage".

Ukraine has neither confirmed nor denied its involvement in a string of recent explosions in Crimea, which Russia annexed in 2014. (Reporting by Reuters; Editing by Alison Williams)
