At least 15 people have been killed after a 10-storey residential apartment building partially collapsed in Russia’s southwestern city of Belgorod on Monday, Russian news agency TASS reported citing the Russian Emergencies Ministry’s statement.

According to the report, the building collapsed following a “Ukrainian attack” on May 12. “Rescuers found another body. In all, 15 bodies have been already recovered from the rubble,” the statement reads. Belgorod and its suburbs came under massive shelling by the Ukrainian armed forces earlier on May 12. Fragments of a downed Tochka-U tactical missile damaged a 10-storey residential building, causing one of its sections to collapse.
