On Sunday, an explosion hit a gas pipeline running from Egypt to Israel. The pipeline, which also supplies gas to Jordan, has come under attack at least 12 times since Mubarak was toppled in 2011. The latest blast took place west of the Mediterranean coastal town of el-Arish. Egypt's 20-year gas deal with Israel, signed in the Mubarak era, is unpopular with some Egyptians, with critics accusing Israel of not paying enough for the gas. Previous explosions have sometimes led to week-long shutdowns along the pipeline. Egypt said in November it would tighten security measures along the pipeline by installing alarm devices and recruiting security patrols from Bedouin tribesmen in the area.
