The MK-82 bombs released by the KF-16 fighter jets fell outside a firing range, the air force said in a statement. It apologized and expressed hopes for a speedy recovery of the injured and said it would offer compensation and take other necessary steps.
The air force said the fighter jets were taking part in the one-day firing drill with the U.S. military in Pocheon, a city close to the heavily armed border with North Korea.
The air force also said a committee would investigate the accident and examine the scale of the damage inflicted.
An unidentified air force official told local reporters that a pilot of one of the KF-16s had entered wrong coordinates for a bombing site. An unidentified Defense Ministry official told reporters that further investigation was needed to determine why the second KF-16 also dropped bombs on a civilian area.
In a televised briefing, Pocheon Mayor Paek Young Hyeun called the bombings “awful” and urged the military to halt drills in the city until it formulates reliable steps that can prevent a recurrence. He said that Pocheon, a city of 140,000 people, provides three major firing ranges for the South Korean and U.S. militaries.
Park Seong-sook, a 70-year-old eyewitness who was not hurt in the bombing, said she thought “a war has broken out.”
“It was such a loud sound,” she said, adding that it left her trembling with fear.
The military said later Thursday it has decided to suspend all live-fire drills across South Korea.
