Attackers early Tuesday blown up a terminal of the Egyptian pipeline pumping natural gas to Israel and Jordan in the second attack on the pipeline in eight days. The blast reported in the early hours of Tuesday morning in the city of El-Arish in the northern part of Egypt's Sinai Peninsula near the border with Israel, the Associated Press reported. The attackers ordered the guards to leave and then blew up the terminal. There were no casualties, sources said. Following an April attack, the Egyptian authorities said they had stepped up security measures along the 192-kilometer pipeline. It was the fourth attack on the pipeline since the ousting of Hosni Mubarak's regime on February 11. Egypt provides up to 45 percent of Israel's gas imports.
