Two members of the United States military are dead after a U.S. Army helicopter crashed Monday night just outside South Korea’s capital, Seoul.

According to the U.S. Army, the chopper was an Apache AH-64. It went down on a road in Wonju, about 50 miles east of the U.S. Camp Humphrey’s military installation.

This from the BBC:

The Army has not identified the dead crew members, but said they were both pilots – no other casualties or damage were reported.

The US has about 29,000 troops in South Korea under a security deal.

South Korea’s Yonhap news agency said the cause of the crash was being investigated, but that officials believe it may have hit power lines.
