Two South Korean fighter jets accidentally dropped eight bombs in a civilian area during a joint exercise with the US military on Thursday, injuring 15 people, officials said.
The MK-82 bombs dropped by KF-16 fighter jets fell outside the firing range, the air force said in a statement. It apologized and expressed hope for a speedy recovery for the injured, and said it would offer compensation and take other necessary steps.
The air force said the fighter jets were taking part in a one-day exercise with the US military in Pocheon, a city near the heavily armed border with North Korea.
The Air Force also said a committee will investigate the accident and examine the extent of the damage caused.
An unidentified Air Force official told local reporters that a pilot of one of the KF-16 aircraft had entered the wrong coordinates for a bombing site. While a Defense Ministry official told reporters that further investigation was needed to determine why the second KF-16 also dropped bombs in a civilian area.
In a televised news conference, Pocheon Mayor Paek Young Hyeun called the bombings "horrific" and asked the military to halt drills in the city until it can formulate credible steps that can prevent a repeat of the event. He said Pocheon, a city of 140,000, provides three major firing ranges for the South Korean and U.S. militaries.
Park Seong-sook, a 70-year-old eyewitness who was not injured in the bombing, said she thought "a war had broken out."
"It was such a loud sound," she said, adding that it left her shaking with fear.
The military later said it has decided to suspend all live-fire exercises across South Korea.
The accident occurred shortly before the South Korean and US militaries announced that they would begin annual large-scale military exercises next Monday.
It is unclear how long the suspension of training will last, but observers said it is likely to be until the military determines the cause of Thursday's accident and devises preventive steps.
