Hundreds of Egyptian demonstrators have blocked a main Cairo bridge over the Nile river to back their call for an end to military rule.

The protesters stopped traffic on the Oct. 6 bridge during Thursday's peak traffic period. Angry commuters argued with them.

The bridge blocking was a prelude to a larger gathering. Many Egyptian groups, including Islamists, plan to join a Friday demonstration calling for a quick end to military rule.

Egypt's military took power after longtime President Hosni Mubarak was deposed in a popular uprising in February 2011.

Egypt's transition has been marked by mistrust, mismanagement and violent clashes between protesters and security forces.

Some Egyptians fear the ruling generals won't hand over power to civilians by the end of June, as they have promised.
