A US F-16 fighter jet has crashed into the Yellow Sea, west of the Korean Peninsula.
US forces in South Korea say the crash occurred after an "in-flight emergency" on Wednesday morning. They say the aircraft belongs to Kunsan Air Base in the central part of South Korea.
The US forces say the pilot was rescued after safely ejecting. They say he is conscious.
South Korean media report that the crash site is in the same area as an island used by US and South Korean air forces for bombing drills.
The US military is investigating how the incident happened.
In May, a US F-16 fighter crashed into farmland in Pyeongtaek, south of Seoul. About seven months later, another US F-16 went down into the Yellow Sea.
