A U.S. government official told The Associated Press on Friday that a test of the Taepodong-2 may be imminent. The Washington official agreed to speak but only on the condition of anonymity because of the sensitivity of the information. South Korean newspaper Chosun Ilbo reported Saturday that North Korea also moved about 10 fuel tanks to the launch site in preparation for the test. It said intelligence authorities from Seoul and Washington had made the assessment, based on satellite images, that the North had loaded booster rockets onto a launch pad and moved the fuel tanks close by. The paper quoted an unidentified high-level South Korean government official. Japan's conservative daily Sankei reported that the North Korean government has ordered its people to raise the national flag at 2 p.m. Sunday (5 a.m. GMT) and to watch a state message on television in the late afternoon. Sankei, citing government officials it did not name, said the Japanese government had dispatched two Aegis destroyers to the Sea of Japan and the Pacific Ocean. Hidetsugu Iwamasa, a Japanese naval official, said he could not comment on the report, citing security concerns. North Korea plans to disguise the missile test as an attempt to put a satellite into orbit, Kyodo reported Saturday. Pyongyang has been calculating an orbit for a fake satellite and plans to announce its trajectory after firing the missile, Kyodo reported from Beijing, citing military intelligence officials it did not identify. North Korea said in 1998 that its launch then was an effort to put a satellite in space, but Washington and Tokyo say that is just a cover for a military program.
