Four South Koreans died after their car crashed into a U.S. armored vehicle on Sunday night in Pocheon, north of Seoul.
The two couples were heading home when their sport utility vehicle rear-ended a U.S. armored vehicle around 9:30 p.m. near the Rodriguez Live Fire Range.
All in their 50s, the occupants were pronounced dead after being taken to a nearby hospital and receiving emergency treatment, including CPR.
One American soldier sustained a minor injury and was taken to a hospital.
The SUV's engine was damaged beyond recognition after the crash, while the armored vehicle's caterpillar tracks on the right side were damaged.
U.S. soldiers in the armored vehicles were on their way to their base in Cheorwon, Gangwon Province, after a drill, the police said, adding that the road where the accident occurred was frequently used by U.S. armored vehicles.
