The Egyptian branch of the Islamic State group has claimed responsibility for a string of terror attacks in the Sinai Peninsula that have claimed the lives of 32 people and injured dozens. The attacks were meant to coincide with the anniversary of the 2011 Egyptian uprising. In the nearby Gaza Strip, Palestinians are concerned that an escalation of the conflict in Egypt could affect the Rafah border crossing, the only overland route to the outside world.
