An explosion has destroyed an Egyptian pipeline in Sinai that supplies Israel and Jordan with gas.
Security sources say the explosion happened west of the city of al-Arish on Tuesday.
Witnesses say 15-metre high flames could be seen shooting up from the pipeline, Reuters reports.
The cause of the blast was not immediately known and there were no immediate reports of casualties.
The pipeline has been repeatedly blown up by assailants believed to be opposed to selling Egyptian gas to Israel since President Hosni Mubarak was ousted in February this year.
The last attack occurred in July when men with machine guns in a small truck forced guards at a station out and blew it up.
The pipeline is run by Gasco, Egypt's gas transport company which is a subsidiary of national gas company EGAS.
