Morsi supporters clash with police
Hundreds of supporters of Egypt's ousted President Mohammed Morsi have clashed with security forces in Cairo, BBC reported.
Police used tear gas to drive back protesters, some hurling rocks, who temporarily blocked an arterial route through the capital.
The clashes came after a senior US envoy said Egypt had been given a "second chance" to create a democracy.
He met Egypt's new interim leaders but was snubbed by key groups including Mr Morsi's Muslim Brotherhood.
The clashes took place a week after more than 50 Morsi supporters were killed in fighting with troops outside the Republican Guard compound where the former president is believed to be being held.
Mr Morsi was ousted in a popularly backed military coup on 3 July.
Monday's battles erupted after hundreds of angry protesters blocked the main 6 October bridge. The bridge later reopened with no reports of casualties.
Earlier, large crowds of pro-Morsi demonstrators were also reported outside the Rabaa al-Adawiya mosque, where they have been holding a round-the-clock vigil to demand Mr Morsi's reinstatement, and at Cairo University.
"Get out, Sisi," some shouted, referring to the head of the armed forces, General Abdel Fattah al-Sisi, who oversaw the overthrow of Mr Morsi.
Meanwhile, officials said suspected Islamist militants had attacked a bus carrying workers to a cement factory in north Sinai, killing three people. Fourteen others were wounded.
