Egyptian security officials say an explosion hit a gas pipeline supplying gas to Israel and Jordan.
The officials say the blast early Monday occurred near the northern coastal town of Al-Arish in Egypt's Sinai Peninsula.
It was the 14th such attack on the pipeline since 2011, when the uprising against President Hosni Mubarak began. The pipeline has been shut since the last attack earlier this year.
No one has claimed responsibility for Monday's blast.
Egypt and Israel signed a gas deal during Mr. Mubarak's presidency, under which Egypt would export gas to its northern neighbor. However, the deal was unpopular with the Egyptian public.
Last year, Egyptian police arrested a leading member of an armed Islamist group suspected in connection with several of the bombings.
