North Korea has lambasted the U.S. for relisting it as a state sponsor of terrorism, calling the move a "serious provocation" and vowing to continue building up its "treasured nuclear sword."

"The U.S., the kingpin of all kinds of terrorism who cannot even prevent terror in its own territory, is acting like an 'international judge on terrorism' while attaching or removing the label of 'state sponsor of terrorism' on sovereign countries," the North's official Korean Central News Agency quoted a Foreign Ministry spokesperson as saying late Wednesday. "This is clearly an absurdity and a mockery to the world peace and security."

The remarks were the first from Pyongyang since U.S. President Donald Trump announced Monday the designation to re-list North Korea as one of just three other countries as state sponsors of terrorism. North Korea was removed the list in 2008 as part of an attempt to salvage international talks aimed at halting it nuclear ambitions, but the talks, which involved six countries including Japan, collapsed soon after and haven't been revived since.
