South Korea's military said on Monday it had tracked a North Korean balloon over its territory, but determined it did not pose a threat.
The balloon briefly entered South Korean airspace on Sunday, the Ministry of Defense said in a statement, adding it in response had taken unspecified “measures”.
The craft left South Korean airspace a few hours later and officials believe it was a weather balloon not one intended for spying activities, Yonhap news agency reported, citing an unnamed official.
