Still heating up.

CAIRO — Egypt’s ruling party said Thursday it was ready for a dialogue with the public but offered no concessions to address demands for a solution to rampant poverty and political change heard in the country’s largest anti-government protests in years.

At the same time, the grass roots protest movement was getting a double boost likely to energize the largest anti-government demonstrations Egypt has seen in years. Mohammed ElBaradei, a Nobel peace laureate and the country’s top pro-democracy advocate, was returning to the country Thursday night and declared he was ready to lead the protests. The country’s largest opposition group — the fundamentalist Muslim Brotherhood — also threw its support behind the demonstrations.

Rioting and protests erupted for a third straight day and social networking sites were abuzz with talk that Friday’s rallies could be some of the biggest so far calling for the ouster of President Hosni Mubarak after 30-years in power. Millions gather at mosques across the city for Friday prayers, providing organizers with a huge number of people already out on the streets to tap into.

The protesters have already achieved a major feat by sustaining their demonstrations for three days in the face of a brutal police crackdown. Seven people have been killed, hundreds hurt and nearly 1,000 detained.

The government has banned all gatherings and police have fired rubber bullets, tear gas, and used water cannons to disperse crowds. They have also fired live ammunition in the air at time to warn people and there have been many scenes of riot police in helmets and shields charging crowds and beating people with batons and plainclothes police beating demonstrators with long sticks.
