The blast, near El-Arish and approximately 30 miles south of the Israeli border, forced the evacuation of nearby residents from their homes.
Unlike the that cut supplies to Jordan and Israel, the latest attack apparently was planned to affect Israel exclusively, and gas to Jordan continues to flow. The gas was shut off from Port Said to prevent continuing fires from the gas that had escaped from the pipeline after the attack. However, gas in the pipeline still is flowing to Israel for a limited amount of time.
Egyptian officials have not identified the terrorists who struck Wednesday morning, but Bedouins have taken de facto control over large parts of the northern Sinai since the uprising that ousted Hosni Mubarak as Egyptian president.
The latest attack comes on the heels of a new showing that a majority of Egyptians want to cancel the 1979 peace treaty that recognized Israel and initiated diplomatic relations with the Jewish State.
Egyptian officials earlier this week also announced that Mubarak and former aides are under investigation for alleged corruption concerning the 20-year agreement to export gas to Israel.
