Egypt imposes state of emergency in Sinai after attacks -BBC

“There has been no claim of responsibility for Friday’s suicide blast at an army checkpoint that killed 28 soldiers.
At least 28 others were injured in the attack near El Arish, the main town in the north of the restive peninsula.
Three more soldiers died in a separate shooting at a checkpoint in the town itself.”

“The area has become increasingly lawless since President Hosni Mubarak was overthrown in 2011. Militants have stepped up attacks since Islamist President Mohammed Morsi was ousted by the army last year.”
