Cairo: A recently emerged Egyptian militant group claimed responsibility for a bomb attack in Cairo on Friday that killed six policemen and wounded three others.

The Hasm Movement, which has claimed several attacks in Egypt in recent months, said it set off the bomb which security sources said also injured f our civilians.

The attack, at a police checkpoint on a main road that leads to the Pyramids, was the latest in a series of security incidents in Egypt claimed by radical Islamists.

The policemen were either in or near their car when the device went off, the security sources said.

The interior ministry said a security cordon had been thrown around the scene of the attack near a mosque.

Eyewitness Ahmad Al Deeb described a scene of carnage, with dead and dying policemen lying next to wrecked cars. One of the policemen had blast fragments in his chest and two others had lost their legs, he told Reuters Television.

Security forces killed three gunmen on Tuesday in a raid on a hideout in southern Egypt that they said was used by Hasm, which they described as an armed wing of the Muslim Brotherhood.
