Two South Korean air force planes collided in mid-air during training and crashed near their base on Friday, killing all four people on board, officials said.

Both planes were KT-1 trainer aircraft, South Korea’s first indigenously developed planes, which took off from an air force base in the south-eastern city of Sacheon one after another for flight training, the air force said in a statement.
