SEOUL: The influential sister of North Korean leader Kim Jong Un vowed again Sunday to push for a second attempt to launch a spy satellite as she lambasted a UN Security Council meeting over the North's first, failed launch.

The North's attempt to put its first military spy satellite into orbit last Wednesday failed as its rocket crashed off the Korean Peninsula's western coast. An emergency meeting of the UN Security Council was still convened at the request of the US, Japan and other countries to discuss the launch because it had violated council resolutions banning the North from performing any launch using ballistic technology.
