At least four explosions hit an area near a major Russian military airport in the peninsula of Crimea on Thursday, three local sources said, but a pro-Moscow official said no damage had been done, APA reports citing Reuters.
The sources said the blasts occurred in the vicinity of the Belbek base, north of Sevastopol.
The governor of Sevastopol, citing what he called preliminary information, said Russian anti-aircraft forces had downed a Ukrainian drone.
"There is no damage. No one was hurt," said Mikhail Razvozhayev, writing on Telegram.
Footage posted to a Ukrainian news-gathering site showed what appeared to be a rocket being fired into the night sky and the sound of at least two explosions. Reuters was unable to immediately verify the veracity of the footage.
