The South Korean authorities have found what they believe to be the fuselage of a firefighting helicopter that crashed into the sea last night.
Seven people were on board, including one patient,... and all of them are still missing.
A full-scale search and rescue operation has been underway, with the defense ministry dispatching 45 personnel along with patrol boats and aircraft.
The helicopter crashed near Korea's eastern most islets of Dokdo at around 11:30 PM, just three minutes after takeoff.
President Moon has ordered a general inspection of that particular model of helicopter.
