The death toll in the storms that battered the Oklahoma City area late last week has risen to 13, including four children, authorities said Sunday.
The chief medical examiner's office said the storm claimed the lives of nine adults and four children. Three of the adults have been identified as professional storm chasers.
A total of 115 people were treated in Oklahoma City area hospitals for injuries, the Oklahoma State Department of Health said Sunday. Thirteen tornadoes struck the region over three days last week, including five in the metropolitan area on Friday.
State emergency officials in Oklahoma will begin working Monday with the Federal Emergency Management Agency and local emergency managers to assess the damage for potential federal aid, the Oklahoma Department of Emergency Management said in a statement.
