A fire killed 8 people in a Moscow hostel where bars on the windows prevented occupants from escaping escape, authorities said, writes Associated Press.

The fire broke out late Thursday in the hostel, which was located in a multi-story apartment building in the Russian capital’s far southeast. The cause of the blaze has not been determined.

About 200 people who lived in the building fled the fire. 4 people were hospitalized.

The chairman of the Moscow city council’s safety committee, Kirill Shitov, said he had previously reported safety violations at the hostel to authorities but no action was taken.
