N.Korean Drone 'Too Small' for S.Korean Radars to Detect

Defense Minister Han Min-koo on Wednesday said that a North Korean drone that was found to have spied on the Terminal High-Altitude Area Defense battery could have been mounted with "bombs or chemical and biological weapons."

Han made the comments before the Defense Committee at the National Assembly.

"I believe North Korea's aerial surveillance of the THAAD battery shows that it wants to bomb the installation in an emergency situation," Han added. 

Asked why the drone evaded detection, Han said, "It measures around 2 m, which is the smallest among North Korea's drones and it is too small to be detected by our equipment."

He added, "I believe that is why North Korea used it to spy on our rear defense areas."
