SEOUL, South Korea -- North Korea vowed on Thursday to launch a pre-emptive nuclear strike against the United States, amplifying its threatening rhetoric hours ahead of a vote by U.N. diplomats on whether to level new sanctions against Pyongyang for its recent nuclear test.
An unidentified spokesman for Pyongyang's Foreign Ministry said the North will exercise its right for "a preemptive nuclear attack to destroy the strongholds of the aggressors" because Washington is pushing to start a nuclear war against the North.
Although North Korea boasts of nuclear bombs and pre-emptive strikes, it is not thought to have mastered the ability to produce a warhead small enough to put on a missile capable of reaching the U.S. It is believed to have enough nuclear fuel, however, for several crude nuclear devices.
Such inflammatory rhetoric is common from North Korea, and especially so in recent days. North Korea is angry over the possible sanctions and over upcoming U.S.-South Korean military drills. At a mass rally in Pyongyang on Thursday, tens of thousands of North Koreans protested the U.S.-South Korean war drills and sanctions.
Army Gen. Kang Pyo Yong told the crowd that North Korea is ready to fire long-range nuclear-armed missiles at Washington.
"Intercontinental ballistic missiles and various other missiles, which have already set their striking targets, are now armed with lighter, smaller and diversified nuclear warheads and are placed on a standby status," Kang said. "When we shell (the missiles), Washington, which is the stronghold of evils, .... will be engulfed in a sea of fire."
The U.N. Security Council is set to impose a fourth round of sanctions against Pyongyang in a fresh attempt to rein in its nuclear and ballistic missile programs.
Russia's U.N. Ambassador Vitaly Churkin, the current council president, said the council would vote on the draft sanctions resolution Thursday morning.
The resolution was drafted by the United States and China, North Korea's closest ally. The council's agreement to put the resolution to a vote just 48 hours later signaled that it would almost certainly have the support of all 15 council members.
The statement by the North Korean Foreign Ministry spokesman was carried by the North's official Korean Central News Agency.
It accused the U.S. of leading efforts to slap sanctions on North Korea. The statement said the new sanctions would only advance the timing for North Korea to fulfill previous vows to take "powerful second and third countermeasures" against its enemies. It hasn't elaborated on those measures.
The statement said North Korea "strongly warns the U.N. Security Council not to make another big blunder like the one in the past when it earned the inveterate grudge of the Korean nation by acting as a war servant for the U.S. in 1950."
North Korea demanded the U.N. Security Council immediately dismantle the American-led U.N. Command that's based in Seoul and move to end the state of war that exists on the Korean Peninsula, which continues six decades after fighting stopped because an armistice, not a peace treaty, ended the war.
In anticipation of the resolution's adoption, North Korea earlier in the week threatened to cancel the 1953 cease-fire that ended the Korean War.
