An explosion was reported Friday near a cafe in the southwestern Russian city of Taganrog near the border with Ukraine, injuring at least 15 people, according to the governor.
"A rocket supposedly exploded. Rescuers are at the scene. There are no dead. There are several injured to whom ambulances have been dispatched," Rostov region governor Vasily Golubev said on Telegram, later adding that 15 people suffered "light injuries."
Russian Defense Ministry said the accident was caused by debris of a Ukrainian missile that it intercepted.
"Russian air defense equipment detected the Ukrainian missile and intercepted it in the air. The debris of the downed Ukrainian missile fell on the territory of Taganrog," the ministry said in a statement.
The Ukrainian side has not responded to the accusation yet.
