(KYTX/CNN) - A powerful blast rocked the Russian region of the Urals early this morning.
Emergency crews there say bright objects, identified as possible meteorites, were seen falling from the sky. One person living there says they heard a huge blast and felt a shockwave in a 19-story building. The sounds of car alarms and breaking windows could also be heard in the area.
More than 400 people were injured. Four people were hurt by broken shower windows. There were also some reports of damage -- part of a roof at a zinc factory collapsed.
Authorities are patrolling the skies with three aircraft to try to detect any future events.
