Egypt's political forces have called for more protests on Friday, June 22, against the ruling military's power grab, as the nation nervously awaits the results of the first post-Mubarak presidential election.

Hundreds of people spent the night in Cairo's Tahrir Square, with more protests planned for Friday afternoon, the Muslim Brotherhood and secular movements said in statements.

The ruling Supreme Council of the Armed Forces (SCAF), which took power when Hosni Mubarak was ousted last year, will issue a statement at 1130 GMT, state television said without providing any details, as anger mounts over the perceived threat to the fragile democratic gains made since the uprising.

The Muslim Brotherhood, which claimed its candidate Mohamed Morsi had won the divisive election against ex-premier Ahmed Shafiq, has been holding crisis talks with the country's political forces.
