North Korea didn’t launch its rocket Saturday and Seoul ended its emergency state of alert ― for now.

South Korean President Lee Myung-bak Saturday convened an emergency meeting of his top security officials in the basement bunker at the presidential office of Cheong Wa Dae, Yonhap News Agency said.

"The emergency meeting has ended. We believe the North will not fire the rocket today," an official from the presidential office told reporters, asking not to be identified.

North Korea said it would launch a communications satellite from 11 a.m. to 4 p.m. between April 4-8 from its Musudan-ri facility in the northeastern part of the country.

Japan, South Korea and the U.S. suspect it may be a ballistic missile.

Saturday was the first day of the North’s designated timeframe. North Korea, however, didn’t fire the rocket by 4 p.m., the deadline for launch for each day.

In London’s G20 meeting, President Lee Myung-bak said he expected North Korea was likely to fire the rocket Saturday.

CNN cited the weather conditions as the likely reason for Pyongyang's failure to go ahead with its plan.

The security ministers' meeting was convened shortly after President Lee returned from his five-day trip to London where he attended the G-20 economic summit.

North Korea’s official media KCNA Saturday said in a statement that the launch was “imminent.”

"Preparations for launching 'Kwangmyongsong-2,' an experimental communications satellite, by carrier rocket "Unha-2" have been completed," KCNA had said.

The Cheong Wa Dae official said pertinent officials will be on standby again Sunday during the expected launch hours.
