Officials said Saturday that South Korean troops fired at a passenger plane carrying 119 passengers and crew, thinking it was a North Korean warplane.
Two Marine guards on Gyodong island off the western coast of South Korea fired their K-2 rifles (similar to the M-16) at the Asiana plane as it descended for landing Friday at Seoul's Incheon airport.
The passenger liner was on a flight from China and was undamaged, because it was out of range of the rifles.
Officials say the firing lasted about 10 minutes, with the guards discharging around 99 shots.
