Security sources said the explosions were detonated from a distance and that tracks from two vehicles were found in the area. No group has claimed responsibility for the attack.

The pipeline, which supplies gas to Jordan and Israel, was last attacked on Nov. 25. It is the eighth such attack since Mubarak stepped down on Feb. 11.
