Cairo blast kills two, injures nine

A bomb blast in one of the busiest boulevards in Cairo's business district has killed two civilians, according to authorities.

Nine others, including policemen, were injured in Monday's explosion outside the Egyptian High Court.

The bomb was hidden under a car parked near the country's highest criminal court in Cairo's Ramses neighbourhood.

The area is very crowded, with dozens of street vendors selling their wares on stalls set up on the stalls. Nearby are several bus stops, a railway station and a metro station.

Police cordoned off the area and state TV later reported that a second bomb was dismantled before it went off.

A group calling itself Revolutionary Punishment claimed responsibility on its Twitter account for the attack, saying they targeted a police checkpoint.

The group is believed to mostly consist of political activists seeking revenge for the ongoing crackdown on ousted President Mohamed Morsi's supporters.
