CAIRO
Egyptian security forces on Tuesday arrested 400 people suspected of involvement in last night's deadly clashes in downtown Cairo.
A security source said the suspects had been referred to prosecutors to face charges of rioting, according to state-run news agency MENA.
Supporters of ousted president Mohammad Morsi converged on downtown Cairo's central Ramses Square on Monday evening and blocked the nearby 6 October Bridge, one of the Egyptian capital's main arteries, to demand Morsi's reinstatement.
While Morsi supporters have accused security forces of attacking them with tear gas while they were performing nighttime prayers, the Interior Ministry accused them of disrupting traffic and attacking passing vehicles.
The Health Ministry said at least seven people were killed and about 261 injured in yesterday's violence.
Egypt has been in a state of turmoil since the army removed Morsi on July 3, suspended the constitution and installed the head of the country's constitutional court as interim president.
The move followed days of mass protests nationwide demanding the resignation of Egypt's first democratically elected president.
Since then, Morsi loyalists have taken to the streets across the country to defend the deposed president's democratic legitimacy and demand that he return to office.
