Security officials say an explosion has hit the Egyptian pipeline that carries gas to Israel and Jordan.
The Monday morning blast took place in the Sinai Peninsula, near town of Arish, which is just 30 miles from Israel.
The Egyptian officials had no further details. There were no immediate reports of casualties. The officials spoke on condition of anonymity because they are not authorized to talk to the media.
The blast is the third to hit the strategic pipeline since an Egyptian uprising overthrew former President Hosni Mubarak in February.
No one claimed to be behind the explosion. Bedouin tribesmen in the area have attacked the pipeline in the past.
