A curfew was imposed from 8 pm to 7 am as skirmishes between troops and rioters continued. Krayev ordered troops to rescue Armenians left in their apartments. By the evening of the 29th, martial law was imposed and troops in buses and personnel carriers were patrolling the streets of Sumgait. Under heavily armed guard, civilian buses and APCs transported Armenian residents to the Samed Vurgun Cultural Facility (known as the SK) in the city's main square. The SK building was designed to accommodate several hundred people, though as many as several thousand eventually found shelter there.
