Clashes early Saturday pitting supporters of ousted Egyptian President Mohammed Morsi against the police in the eastern Cairo district of Nasr City have left more than 200 people dead and some 4,500 wounded, the Muslim Brotherhood said Saturday.

The Brotherhood, citing sources from the field hospital in this capital's Rabia al-Adawiyya Square, said on its Web site that most of the victims in the clashes had suffered gunshot and birdshot wounds to the head, neck and chest.

The field hospital in Rabia al-Adawiyya, where Morsi's supporters are camped out, has shut its doors because it has no room to treat more victims.

A spokesman for the Muslim Brotherhood's youth movement told Efe there were a large number of dead and wounded at the health clinic and a lack of medicine and specialized doctors.

According to the sources, the clashes ended Saturday morning, although security forces were still deployed in the area.

The Health Ministry thus far has confirmed 38 deaths and 239 people wounded in the clashes, although it said those figures did not include those being treated at Rabia al-Adawiyya.

Conflicting reports have emerged about what triggered the clashes.

The Interior Ministry accused the Muslim Brotherhood, the Islamist group Morsi belonged to prior to becoming president, of firing birdshot at security forces and trying to block the 6th October Bridge, one of the city's main arteries.

The ministry said police only used tear gas against the demonstrators, who, it added, had clashed with residents of Nasr City.

According to the Islamists, police and armed thugs attacked the pro-Morsi demonstrators, firing gunshot and birdshot at their heads and chests.

Morsi's Islamist supporters have held a sit-in protest in east Cairo since he was ousted in a July 3 coup, when the armed forces suspended the constitution that he enacted during his abbreviated term in office and named Adly Mansour, the head of the Supreme Constitutional Court, as interim head of state pending fresh elections.

The military acted following days of massive anti-government protests.

Critics accused Morsi and the Brotherhood of doing little to address poverty and Egypt's struggling economy, of failing to advance the goals of the 2011 revolution that forced out strongman Hosni Mubarak and of seeking to monopolize power. EFE
