South Korea 'crashed drone' turns out to be toilet door

SEOUL (AFP) - South Korea's defence ministry said on Wednesday that a suspected crashed drone spotted by a walker was a false alarm - it was actually the door of a portable toilet.

A passer-by had reported seeing what he thought was the wreckage of a drone caught among rocks and trees in a fenced off military area, while walking on a hillside in southern Seoul.

But an investigation team sent to the area found that the object was actually the broken door of a portable toilet, a defence ministry spokesman said.

The door was a similar sky blue colour to three drones recovered by South Korea in March and April.

"The shape from a distance and the colour was probably what created the confusion," the spokesman said.

Seoul said last week that a joint investigation with US experts had provided "smoking gun" proof that the three recovered drones were flown from North Korea and had been pre-programmed to fly over South Korean military installations.

North Korea angrily denied any link with the drones, accusing the South of "fabricating" the evidence.
