Egyptian police have fired tear gas to disperse crowds of supporters of detained ex-leader Mohammed Morsi during a march in central Cairo on Tuesday, Aug 13, according to BBC News.

Security forces moved in after the pro-Morsi demonstrators clashed with crowds of their political rivals. Witnesses said the two groups threw stones and bottles at each other, and women and children fled the scene.

Morsi was deposed by army leaders in July amid huge protests. The army has since installed an interim government.

Supporters of Morsi, an Islamist leader who came from the Muslim Brotherhood movement, refuse to accept the new government and insist he must be reinstated.

Tuesday's trouble began when crowds of Morsi's supporters marched through an area of Cairo where many people oppose the Muslim Brotherhood. The protesters tried to get into the Ministry of Endowments, but were forced out by police.

Local residents then taunted the protesters, and police moved in to quell the ensuing clashes.

Millions of Egyptians had protested in favor of Morsi's removal, but correspondents say his ousting appears to be deepening the divisions in Egyptian society.
