Egypt has been struggling to quell an insurgency, mainly focused in the north of the Sinai Peninsula, since early 2011.
However the insurgency has increasingly extended outside of the restive peninsula into urban areas with a rise in the number of explosions and shootings in cities, including Cairo.
Most attacks have targeted security forces, especially checkpoints in the restive Sinai Peninsula. However militants have also target state installations and increasingly pursued state officials.
