N. Korea defiantly launches rocket over Pacific SEOUL (AP)  North Korea defiantly carried out a provocative rocket launch Sunday that the U.S., Japan and other nations suspect was a cover for a test of its long-range missile technology. Liftoff took place at 11:30 a.m. Sunday from the coastal Musudan-ri launch pad in northeastern North Korea, the South Korean and U.S. governments said. The multistage rocket hurtled toward the Pacific, reaching Japanese airspace within seven minutes, but no debris appeared to hit its territory, officials in Tokyo said. The U.N. Security Council approved an emergency session for Sunday afternoon in New York, following a request from Japan that came minutes after the launch. The South Koreans called it "reckless," the Americans "provocative," and Japan said it strongly protested the launch. The launch was a bold act of defiance against President Barack Obama, Japanese leader Taro Aso, Hu Jintao of China and others who pressed Pyongyang in the days leading up to liftoff to call off a launch they said would threaten peace and stability in Northeast Asia. South Korea's presidential Blue House said the launch poses a "serious threat" to stability on the Korean peninsula and that it would respond to the provocation "sternly and resolutely." President Lee Myung-bak ordered the military to remain on alert, the Blue House said. "We cannot contain our disappointment and regret over North Korea's reckless act," presidential spokesman Lee Dong-kwan told reporters Sunday. He said the launch of the long-range rocket "poses a serious threat to security on the Korean peninsula and the world." North Korea claims its aim is to send an experimental communications satellite into orbit in a peaceful bid to develop its space program. The U.S., South Korea, Japan and others suspect the launch is a guise for testing the regime's long-range missile technology — one step toward eventually mounting a nuclear weapon on a missile capable of reaching Alaska and beyond. They contend the launch violates a 2006 resolution barring the regime from ballistic missile activity. Obama said Friday the launch would be a "provocative" move with consequences. State Department spokesman Fred Lash said late Saturday in Washington that the U.S. will "take appropriate steps to let North Korea know that it cannot threaten the safety and security of other countries with impunity." He called the launch a clear violation of U.N. Security Council Resolution 1718, adopted five days after North Korea carried out a nuclear weapons test in 2006. Japan's U.N. mission has asked for a meeting of the 15-nation council Sunday, spokesman Yutaka Arima said. Mexico's mission to the United Nations set the meeting for 3 p.m. ET, spokesman Marco Morales said. Mexico holds the 15-nation council's presidency this month. U.N. diplomats already have begun discussing ways to affirm existing sanctions on North Korea against its nuclear program and long-range missile tests. In Japan, chief Cabinet spokesman Takeo Kawamura said it was not immediately clear if the rocket was mounted with a satellite as North Korea has claimed. North Korea calls its "space launch vehicle" Unha-2, but the rocket is better known to the outside world as the Taepodong-2, a long-range missile that can be mounted with a satellite or nuclear armament. "Even if a satellite was launched, we see this as a ballistic missile test and we think this matter should be taken to the United Nations Security Council," Kawamura said. "We are highly concerned by this matter." "We strongly protest this launch," he said. The first stage of the rocket dropped about 175 miles off the western coast of Akita into the waters between Japan and the Korean peninsula. The second stage was to land in the Pacific at a spot about 790 miles off Japan's northeastern coast, a Defense Ministry spokeswoman said in Tokyo. Japan said it would convene a security panel meeting later in the day to discuss what further measures can be taken. Kawamura said Japan would work closely with Washington and with the U.N. "Our primary concern is to confirm safety and gather information," Aso told a news conference at his Tokyo office Sunday. North Korea shocked Japan in 1998 when it launched a missile over Japan's main island. Japan has since spent billions of dollars on developing a missile shield with the United States and has launched a series of spy satellites primarily to watch developments in North Korea. Japan had threatened to shoot down any debris from the rocket if the launch went wrong, and positioned batteries of interceptor missiles on its coast and radar-equipped ships off its northern seas to monitor the launch. No attempt at interception was made since no debris fell onto its territory, a ministry spokeswoman said, speaking on condition of anonymity, citing department rules.
