Ammon News - AMMONNEWS - Two policemen and a passerby were wounded after a bomb exploded in a central Cairo district on Tuesday morning, according to medical and security officials.

The explosive device was placed between two cars, and the blast blew off the roof of a shelter housing traffic police officers near a checkpoint, at a busy intersection in the Dokki neighborhood of Cairo, the Agence France Presse reported.

Egypt has been rocked by a series of bombings and shootings carried out by militants since the military ousted Islamist president Mohammad Mursi in July.

Following his overthrow, authorities installed by former army chief Abdel Fattah al-Sisi quickly moved to repress Mursi's supporters, and in the ensuing crackdown more than 1,400 people have been killed.

Over 15,000 Islamists, mostly members of the Muslim Brotherhood group from which Mursi hails, have also been jailed, while hundreds have been sentenced to death after what are often speedy trials.
