Seoul, Dec 31: North Korea today accused the US military of conducting at least 180 flights to spy on the communist country in December and claimed that Washington was mapping out a surprise attack. The US military used U-2 spy planes and other reconnaissance aircraft for the flights, North Korea's official news agency KCNA reported.

On December 29, an U-2 plane carried out aerial observations over the "whole area" of the democratic people's Republic of Korea, the report claimed.

"Such aerial espionage fully shows that the US imperialists are watching for a chance to make a surprise attack on the DPRK in a bid to stifle it by 'strength,” KCNA said.

North Korea regularly makes such accusations. The US military does not comment on North Korean claims about spy flights, although it acknowledges monitoring the north's military activity. Bureau Report
