Explosions targeted security bases in Sinai on Sunday, left three people injured, according to Egyptian security officials, who speculated militant groups in Sinai could be behind the attack.
A massive explosion partly destroyed the wall of a security base being built for border guards in the town of Rafah at the border with the Gaza Strip overnight, but without causing injuries.
Early on Sunday, large numbers of security forces were deployed at the scene of the explosion and sealed off the area while search for possible explosives was underway, Al Arabiya correspondent reported.
Further south, three workers were injured by a separate blast that damaged a compound being built in Quseima for a different security agency responsible for guarding a pipeline that exports gas to Jordan, security sources said.
Media sources revealed that the explosion in Quseima was caused by a detonating device placed overnight in a building belonging to Egypt’s Central Security Forces, according to the privately-owned Egyptian newspaper Youm 7.
Sinai has been a theater for several bomb attacks over the past months. Disorder has spread in the area since former President Hosni Mubarak was ousted in a popular uprising last year, with Islamists stepping up attacks on security forces on the Israeli border.
The country’s security forces had been fighting Islamist militants in Sinai for several months. Egypt’s new elected Islamist president, Mohammed Mursi, has pledged to restore security in the poor, desert region.
Efforts to impose central authority in the lawless desert region are complicated by the indigenous Bedouin population’s ingrained hostility to the government in Cairo.
