The DPRK warned the United States that it could shoot down U.S. spy planes that entered the state's airspace.
The defense ministry stressed that America will have to pay for the reconnaissance, as it regards it as a provocation accompanied by invasion of DPRK airspace without notice, reports TV channel 360.
Pyongyang said it would shoot down Washington's planes.
From July 2 to 9 there were several similar incidents by the Americans.
Recall that previously the DPRK accused the United States of aggressive actions that could lead to nuclear war on the peninsula.
