North Korea has issued a forceful response to the deployment of a US naval strike group to the region, saying it would counter “reckless acts of aggression” with “whatever methods the US wants to take.”

In a statement provided to CNN by officials in North Korea, Pyongyang said the “current grim situation” justified its “self-defensive and pre-emptive strike capabilities with the nuclear force at the core.”

“We will make the US fully accountable for the catastrophic consequences that may be brought about by its high-handed and outrageous acts,” the statement said.
