North Korea's threat to "weaponize" its plutonium stocks is "provocative" and "deeply regrettable", US Secretary of State Hillary Clinton says. She said the move had been denounced around the world and would isolate North Korea's government further, according to a last night report of BBC. The North said it would start enriching uranium and use the plutonium for nuclear weapons hours after a UN vote for tough new sanctions against it. The US would vigorously enforce the new sanctions, Mrs. Clinton said. Speaking during a visit to Canada, she said that the latest UN moves provided the tools needed for "to take appropriate action" against North Korea. The North says it will view any US-led attempts to "blockade" it as an "act of war". The warning from North Korea's foreign ministry was carried by Pyongyang's official news agency on Saturday.
