KYIV, Aug 17 (Reuters) - Russia blamed sabotage for explosions at one of its military bases in Moscow-annexed Crimea while Kyiv hinted it was responsible as Ukrainian officials said their strategy was to destroy supply lines supporting Russia's invasion.
The blasts on Tuesday engulfed an ammunition depot at a military base in the north of the Crimean peninsula, disrupting trains and forcing the evacuation of 2,000 people from a nearby village, according to Russian officials and news agencies.
Plumes of smoke were later seen at a second Russian military base in central Crimea, Russia's Kommersant newspaper said. The action followed explosions at a Russian military air base in western Crimea last week that destroyed eight warplanes.
Russia's defence ministry said Tuesday's explosions at the ammunition depot were "a result of sabotage". The Crimean peninsula, which Moscow annexed in 2014, is the main supply route for Russian forces in southern Ukraine and the base for its Black Sea fleet.
Ukraine did not confirm or deny responsibility for the explosions though its officials openly cheered Russia's setbacks there.
Presidential adviser Mykhailo Podolyak and chief of staff Andriy Yermak both exulted on social media at "demilitarisation", an apparent mocking reference to the word Russia uses to justify its invasion.
"Operation 'demilitarisation' in the precise style of the Armed Forces of Ukraine will continue until the complete de-occupation of Ukraine's territories," Yermak wrote on Telegram.
Podolyak told Britain's Guardian newspaper later that Ukraine's strategy was to destroy Russian "logistics, supply lines and ammunition depots and other objects of military infrastructure. It's creating a chaos within their own forces."
As Kyiv considers a potential counter-offensive in the south, the explosions raised the prospect of new dynamics in the six-month-old war if Ukraine now has capability to strike deeper in Russian-occupied territory or pro-Kyiv groups are having success with guerrilla-style attacks.
President Volodymyr Zelenskiy urged Ukrainians to steer clear of Russian military bases and ammunition stores and said the explosions could have a number of causes, including incompetence.
"But they all mean the same thing - the destruction of the occupiers' logistics, their ammunition, military and other equipment, and command posts, saves the lives of our people," he said in an evening address.
In Tuesday's blasts, an electricity substation also caught fire, according to footage on Russian state TV. Seven trains were delayed and rail traffic on part of the line in northern Crimea had been suspended, Russia's RIA news agency said.
