Since the ouster of former Islamist President Mohamed Morsi by the army last July, a wave of explosions have targeted security men and their premises in the restive Sinai Peninsula, which have lately extended to hit the capital, the Nile Delta cities and other provinces across the country.
A recent official report said the death toll from such attacks has reached nearly 500, most of whom soldiers and policemen.
The army has launched a large-scale operation since Morsi's removal to uproot the crime hideouts in the restive Sinai. The al- Qaida-inspired Ansar Bayt al-Maqdis group has claimed responsibility for most of the attacks.
