Bomb Kills Policeman in Cairo: Security Sources

A policeman was killed and three others wounded when a bomb exploded on a bridge leading to the upscale Cairo district of Zamalek on Sunday, security sources said, the second bombing targeting police in the Egyptian capital in as many days.

Egypt faces an insurgency that has killed hundreds of soldiers and police officers since the army removed Islamist President Mohamed Mursi in the summer of 2013 following mass protests against his rule.

The force of Sunday's explosion left a crater in the ground. The sources gave conflicting reports about whether the bomb was planted in or near a car.

Two of the wounded were also policemen, while the third was a civilian, they said.

On Saturday, two bombs exploded near a police station in the residential Imbaba district, causing no casualties.

Most attacks have taken place in the Sinai Peninsula, a remote but strategic region bordering Gaza, Israel and the Suez Canal, but smaller-scale bombings have become increasingly common in Cairo and other cities.
