A joint U.S.-Japanese military exercise in the Sea of Japan was suspended when two Russian Il-38 May anti-submarine aircraft flew over the area, the NHK channel said on Wednesday citing the Japanese defense ministry.
The biennial Keen Sword drills were suspended amid fears that the Russian aircraft may obtain top-secret data, the channel reported.
Around 34,000 Japanese military personnel with 40 warships and 250 aircraft joined more than 10,000 U.S. troops with 20 warships and 150 aircraft in the drills in the Sea of Japan, off the southern island of Okinawa.
The agenda of the exercises, which will continue until December 10, include integrated air and missile defense, base security, close-air support, live-fire drills, maritime defense and search and rescue missions.
