N. Korea: At least 170 US spy flights this year

North Korea accused the United States of conducting more than 170 spy flights on its territory in November, the North's official news agency said Thursday. The communist country routinely accuses the U.S. of aerial espionage, issuing a tally of such flights every month. The US military does not comment, although it acknowledges monitoring North Korea's military activity. US spy planes "committed espionage against the DPRK" and "were busy spying on the front-line areas of the DPRK almost every day," said the North's Korean Central News Agency, citing "military sources."
