Helicopter collision kills two battling Greek wildfire

Two crew members were killed when two Greek firefighting helicopters collided midair Sunday while battling a major wildfire west of Athens. The dead were Greek and Danish nationals; two others were injured. Nearly 500 firefighters and 23 aircraft have been deployed, and more than 1,000 people evacuated, over 250 by sea. Strong winds eased Monday, but Attica remains at high risk.
