Fedorishchev, writing on the Telegram messaging app, said four people, including one child, had been rescued from the debris. He did not provide details on casualties or the extent of damage.

The incident occurred in Syzran, a city on the Volga River, amid ongoing hostilities between Russia and Ukraine that have increasingly involved cross-border drone strikes.

Authorities have not released further information on the scale of the attack or whether additional people remain trapped. Rescue teams were continuing efforts at the site, according to the governor’s statement.

There was no immediate comment from Ukrainian officials.
