The Russian-installed governor of Sevastopol, Mikhail Razvozhaev, said a drone was shot down in the Kara-Koba area of the occupied Crimean city amid reports of an explosion.

“According to preliminary data, an UAV (unmanned aerial vehicle) was shot down in the Kara-Koba area. An explosion occurred on the ground, grass and bushes caught fire,” Razvozhaev wrote on his Telegram account Tuesday. “Fire brigades are already at the scene and have started putting out the fire.”

Residents of the city reported hearing a loud explosion on Tuesday afternoon, which shook windows and set off car alarms. Some also said they could see a cloud of smoke rising from the city center.

Both Ukraine and Russia reported cross-border attacks Tuesday. Moscow said Kyiv again attempted a drone strike in Moscow, targeting the exact same building that was hit on Sunday. Kyiv accused Russia of shelling a medical facility in the southern port city of Kherson, killing a doctor and wounding a nurse.
