Arish, Egypt, Ramadan 14, 1434, Jul 23, 2013, SPA - Militants blew up a gas pipeline Tuesday in Egypt's Sinai Peninsula for the second time since the ouster of president Mohammad Morsi this month, a security source said. The bomb, planted at the pipeline that exports gas to Jordan, was detonated remotely. Military helicopters chased a group of masked militants believed to be behind the attack, but they managed to escape, the source was quoted as saying by DPA.
