Egypt has seen a wave of protests and violence since the army
ousted elected Islamist President Mohamed Mursi last year amid
mass protests against his rule.
Army chief Field Marshal Abdel Fattah al-Sisi is expected to run
for president and is widely expected to win by a landslide in an

The Brotherhood denies any links to militants who have carried
out attacks, including bombings in Cairo and the killing of an
Interior Ministry official.
