Fifteen people were injured in South Korea on Thursday after bombs dropped by fighter jets landed in a civilian district, damaging houses and a church during military exercises in Pocheon, the Air Force and the fire agency said.
The fire agency said in a statement that 15 people were wounded, including two who were seriously hurt.
Pocheon is about 40 kilometres (25 miles) northeast of Seoul, near the heavily militarized border with North Korea.
South Korea's Air Force said eight 500-pound (225kg) Mk82 bombs from two KF-16 jets fell outside the shooting range during joint live-fire exercises.
"We are sorry for the damage caused by the abnormal drop accident, and we wish the injured a speedy recovery," the Air Force said in a statement.
The accident was due to a pilot entering incorrect coordinates, said a military official who declined to be identified because of the sensitivity of the matter. The official said that the two jets then dropped four bombs each, with all of them detonating.
