Suspected militants have blown up a pipeline in Egypt's Sinai that transports gas to Jordan in the third such attack in less than a month.
Security officials said there were no immediate reports of injuries in Monday's attack, but witnesses said thick flames rose into the sky from the spot where the pipeline was struck.
They also said that ambulances had rushed to the scene.
Egyptian security officials said the pipeline was blown up in an area called Muqtadiba, south of Al-Arish.
On January 17 and December 31, militants had blown up a section of a pipeline supplying an industrial area in the restive Sinai peninsula.
