Relatives mourn senior Egyptian police officer Brig. Gen. Ahmed Zaki, who was killed after an explosive device placed under his car went off in a western Cairo suburb, during his funeral at the police academy in central, Cairo, Egypt, Wednesday, April 23, 2014. There has been a surge in political violence since former Egyptian President Mohammed Morsi's overthrow in July, 2013. Al-Qaida-inspired and other militant groups have claimed most of the larger attacks on Egyptian troops ? attacks they say are meant to avenge a government crackdown on pro-Morsi and other Islamist protesters.
