Egyptian soldiers and officials inspect the sight where gunmen killed six soldiers at a Cairo checkpoint on March 15, 2014 in an attack the military blamed on the Muslim Brotherhood movement of deposed president Mohamed Morsi. The attack came two days after gunmen killed a soldier in Cairo, as militants once based in the Sinai Peninsula increasingly target the capital in a campaign that has killed more than 200 security men since the army overthrew Morsi last July.
