SEOUL (Reuters) - A North Korean drone briefly entered a no-fly zone surrounding South Korea's presidential office when it intruded into the South's airspace last week, Seoul's military said on Thursday, fuelling criticism over its air defences.

The drone was among five North Korean drones that crossed into the South on Dec. 26, prompting South Korea's military to scramble fighter jets and helicopters. The military was criticised for failing to bring down the drones which flew over the South for hours.
