SEOUL, South Korea (AP) — A South Korean fighter jet accidentally dropped eight bombs on a civilian area during training Thursday, reportedly injuring seven people. The MK-82 bombs “abnormally” released by the KF-16 fighter jet fell outside a firing range, causing unspecified civilian damages, the air force said in a statement.

The blunder near Seoul, which also destroyed buildings, happened during a test run for combined U.S.-South Korea exercises next week.
