North Korea has acknowledged a multi-stage rocket it launched early Friday failed to reach orbit.
An announcer on North Korean television - interrupting programming four hours after the launch, which was not broadcast - says the Kwangmyongsong-3 earth observation satellite did not succeed in reaching orbit and scientific experts are investigating the cause of the failure.
Officials in Seoul, Tokyo and Washington say North Korea's rocket indeed blasted off from the launch pad but failed to get very far.
U.S. military officials called it a Taepo Dong-2 missile. They say it was tracked by satellite on a southern trajectory where the first stage fell into the Yellow Sea. The North American Aerospace Defense Command says the other two stages failed to continue in flight and never posed a threat.

South Korean army major general Shin Won-sik, speaking to reporters at the defense ministry, says the missile began tumbling back to Earth at an altitude of 151 kilometers, separating into about 20 pieces and harmlessly falling into the Yellow Sea 100 to 150 kilometers offshore.
The general says the launch clearly violates UN resolutions 1718 and 1874 and was a test-firing of a long-rang missile disguised as a satellite launch. He adds this is a grave provocation and a serious military threat to international society and the Republic of Korea.
Japan's defense forces, along with the South Korean and U.S. militaries in the region, had deployed anti-missile batteries on land and at sea to possibly shoot down the object if it flew over Japanese or South Korean territories.
Authorities in Japan's southern Okinawan islands, which are close to the intended flight path, activated public address loudspeakers soon after the launch.

South Korea's foreign minister, Kim Sung-hwan, strongly condemns the North going ahead with the launch.
Kim says it is truly regrettable that North Korea spends huge financial resources on developing nuclear weapons and missiles while its citizens are experiencing such hardships.
Japan is echoing similar sentiments, adding it is considering additional financial sanctions on North Korea.
