North Korea on Monday threatened to mount a "preemptive nuclear strike" on South Korea and the United States as the allies kicked off their annual military exercise aimed at countering Pyongyang's potential aggression.

The command and control exercise Ulchi Freedom Guardian, began its two-week run on Monday, involving tens of thousands of South Korean and U.S. forces.

This year's drill came amid unusually heightened inter-Korean tensions following the defection of a London-based North Korean senior diplomat to South Korea.

South Korea and the U.S. "should bear in mind that if they show the slightest sign of aggression on (DPRK's) inviolable land, seas and air ..., it would turn the stronghold of provocation into a heap of ashes through Korean-style preemptive nuclear strike," an English-language statement by the country's General Staff of the Korean People's Army (KPA), carried by the state-run Korean Central News agency, said.
