Powerful explosions rocked a Russian air base in Crimea on Tuesday, and at least five people, including a child, were wounded, authorities said.
Russia's Defense Ministry said that munitions blew up at the Saki base, and it emphasized that the installation had not been shelled.
But Ukrainian social networks were abuzz with speculation that it was hit by Ukrainian-fired long-range missiles.
There was no immediate comment from Ukrainian authorities.
Videos posted on social networks showed sunbathers fleeing a nearby beach as huge clouds of smoke from the explosions rose over the horizon.
Crimea’s head Sergei Aksyonov said ambulances and medical helicopters were sent to the Saki air base and the area was sealed off within a radius of five kilometers.
Five people were wounded, and one of them was hospitalized, said Konstantin Skorupsky, the head of Crimea’s health care department.
