A U.S. Apache helicopter crashed in central South Korea on Monday, killing its pilot and another crew member, police and military officials said, according to Reuters. The attack helicopter went down in the county of Wonju in Gangwon province, the officials said. On Monday, South Korea's military conducted artillery live-fire drills on islands near a disputed maritime border with North Korea, ignoring Pyongyang's threat to fire back if any of the shells landed in its waters.
