U.S. officials say a team of 19 firefighters died Sunday while battling an Arizona wildfire about 130 kilometers northwest of Phoenix. The United States Wildland Firefighters Association confirmed the deaths on its Facebook page. A state forestry official, Art Morrison, told CNN the firefighters were an elite crew. He said it appeared the fire overtook them, and by the time other firefighters reached them, they had been killed.
