'Ukraine’s defence ministry said in a tongue-in-cheek statement that it "could not establish the cause of the fire but would like to once again remind about fire safety and the danger of smoking at inappropriate locations".
But in a thinly-veiled confirmation of Ukrainian involvement, Mikhail Podolyak, an adviser to President Volodymyr Zelensky, said: "The future of the Crimean peninsula is to become a pearl of the Black Sea, a national park with unique landscapes and a global resort, not a military base for terrorists. This is just the beginning."
Meanwhile, Phillips P O’Brien, a professor of strategic studies at St Andrew’s University, said that the actions of the Ukrainians were "extremely important".
"By showing they can hit Crimea, they will further stretch Russia's defensive capabilities. The Russians are going to have to protect a huge area behind the front lines," he said.'
