SEOUL, South Korea — Leaders of South Korea and Britain urged North Korea to forgo its planned rocket launch as international pressure mounted on the communist regime just days before the impending launch.
North Korea says it will send a communications satellite into orbit on a multi-stage rocket between April 4 and 8. The U.S., South Korea and Japan think the communist regime is using the launch to test long-range missile technology, and they warn Pyongyang would face sanctions under a U.N. Security Council resolution banning the country from ballistic activity.
British Prime Minister Gordon Brown said in a summit with South Korean President Lee Myung-bak in London on Tuesday that Pyongyang's launch would be a breach of the U.N. resolution and pledged to respond to it in step with Seoul, Lee's office said.
Lee, in London for the G-20 summit, told Brown it is important for the international community to show a concerted response to the North's move, his office said.
And in the Netherlands, U.S. Secretary of State Hillary Rodham Clinton warned the North would face "consequences" in the United Nations Security Council in the event of a launch.
She also strongly backed Japan's plans to shoot down any incoming North Korean rocket debris, saying the country "has every right to protect and defend its territory from what is clearly a missile launch."
Earlier Tuesday in Tokyo, Japanese Prime Minister Taro Aso said he is ready to pursue punishment by the Security Council if North Korea fires the rocket.
Japan has deployed battleships and Patriot missile interceptors off its northern coast to shoot down any wayward rocket parts that the North has said might fall over the area.
Tokyo has said it is only protecting its territory and has no intention of trying to shoot down the rocket itself, but North Korea said it is not convinced and accused Japan of inciting militarism at home to justify developing a nuclear weapons program of its own.
If Japan tries to intercept the satellite, the North's army "will consider this as the start of Japan's war of re-invasion ... and mercilessly destroy all its interceptor means and citadels with the most powerful military means," the North's official Korean Central News Agency said Tuesday.
Daniel Pinkston _ a Seoul-based expert for the International Crisis Group think tank, which provides detailed analysis about North Korea _ said the communist nation has two underground nuclear warhead storage facilities near bases for its medium-range Rodong missiles, which are capable of striking Japan. The North is believed to have five to eight warheads, he said.
But he stressed it is unclear if the communist nation has mastered the technology necessary to miniaturize the warheads and put them on Rodong missiles, which have a range of 620 to 930 miles (1,000 to 1,500 kilometers).
The National Intelligence Service, South Korea's main spy agency, said it could not confirm Pinkston's claims.
Pinkston said he obtained the information from intelligence officials from a country or countries that he wouldn't identify.
"Their assessment is that North Korea has deployed" and assembled "nuclear warheads for Rodong missiles," Pinkston told The Associated Press.
Two U.S. destroyers are believed to have departed from South Korea to monitor the rocket launch. South Korea is also dispatching its Aegis-equipped destroyer, according to a Seoul military official who asked not to be named, citing department policy.
North Korea claimed Tuesday that the U.S. and South Korea have conducted about 190 spy flights over its territory in March, including over the sea off the launch site on its northeast coast.
Adding to the complexity of the situation, the North announced Tuesday it will indict and try two American journalists accused of crossing the border illegally from China on March 17 and engaging in "hostile acts."
