North Korea threatens "unprecedented" action.

(RT) ⸻ North Korea has warned that it will take "unprecedentedly persistent and strong counteractions" if South Korea and the US go ahead with planned military exercises on the Korean Peninsula. The US and South Korea are set to hold more than 20 rounds of war games next month, as well as conducting the largest-ever example of field exercises between the two nations. South Korea's deputy minister of national defense policy, Heo Tae-keun, announced that Seoul and Washington will conduct computer-simulated training in mid-March, which they say is defensive in nature and designed to counteract a North Korean nuclear threat. Pyongyang warned earlier this month that the expansion of Washington's military exercises with Seoul are pushing tensions towards an "extreme red line." Seoul has expressed renewed concerns about North Korea's nuclear weapons program, after it introduced a new law last year which authorizes the launch of a preemptive nuclear strike under certain conditions.
