Egyptian security forces have fired tear gas at protesters who hurled firebombs at them in central Cairo, according to AP.
The news comes hours after hundreds of opponents to President Mohammed Mursi rallied peacefully in the streets denouncing his rule and demanding early presidential elections.
Despite the low turnout, organizers of the Tamarod or rebellion campaign claim to have collected 2 million signatures on a petition to oust Mursi and hold early elections.
Demonstrators marched through various parts of Cairo before converging on Tahrir Square in a rally which was called for by a number of opposition groups.
The opposition accuses Mursi of governing only in the interests of his Muslim Brotherhood, while he insists he is the “president of all Egyptians.”
Since Mursi was elected last June, Egypt has continued to suffer from a serious political and economic crisis, and there have often been frequent clashes, sometimes deadly, between his opponents and supporters.
