Bloomberg reports: North Korea’s military escalated its threats, citing a law ratified this week as authorizing plans for “counter-actions” against U.S. aggression, including use of a “cutting-edge smaller, lighter and diversified nuclear strike.”

Kim Jong Un’s regime, which hasn’t demonstrated it has a nuclear weapon or a missile capable of delivering one to the U.S. mainland, didn’t elaborate on the armaments it claimed to have in a statement today by a military spokesman, which was distributed by the state-run Korean Central News Agency.

The warning was presented as a response to what North Korea called an “ever-escalating U.S. hostile policy,” citing moves including the use of long-range bombers in a U.S.-South Korea exercise being conducted this month. While tensions have escalated over North Korea’s nuclear weapons program and United Nations sanctions against it, U.S. officials have emphasized this week that they have seen no unusual troop movements by North Korea.
