CAIRO - Opponents of Egyptian President Hosni Mubarak's embattled regime on Sunday dismissed as insufficient an offer to include them in political reform plans, and renewed their demands that he step down.

Newly installed Vice President Omar Suleiman talked with the opposition groups, which included Muslim Brotherhood, but the talks produced no breakthrough in the two-week-old standoff, AFP reported.
As night fell, central Cairo's now iconic Tahrir Square was still filled with hundreds of thousands of anti-regime protesters, adamant that the start of dialogue will not divert them from their campaign to unseat Egypt's dictator.
“It's bullshit. That's my honest opinion,” said 25-year-old Nora Abul Samra. “When he leaves they can do whatever they want. They still believe there is a constitutional way to do it, but this is a revolution.”
One of the leaders from Muslim Brotherhood told Al Jazeera that the Brotherhood did not trust the Egyptian authorities to follow through on promised reforms.
The Brotherhood said that it was not prepared to drop its central demand of calling for Mubarak to resign as president.
“We cannot call it talks or negotiations. The Muslim Brotherhood went with a key condition that cannot be abandoned... that he (Mubarak) needs to step down in order to usher in a democratic phase,” Abdul Moneim Aboul Fotouh, a member of the Brotherhood, told Al Jazeera.
Mahmud Ezzat, the Brotherhood's number two leader, told AFP by telephone that the group had not pulled out of the talks because it felt it had made progress, but warned that street protests would continue.
In his view, by sitting down with the opposition, the regime had tacitly “admitted that this is a popular revolution and its demands are legitimate. And one of our demands is that the president must leave.”
Asked whether he believed Mubarak would step down, Ezzat said: “That hinges on popular pressure, and we support the popular pressure. It must continue.”
The developments came as pro-democracy rallies continued across the country on Sunday -- the 13th day of protests in Egypt.
About a million people were reported to be observing a “Day of the Martyrs” in Tahrir Square calling for an end to Mubarak's 30-year rule. An Al Jazeera correspondent, Ayman Mohyeldin, who was at the square, was arrested by the military on Sunday afternoon.
Both Muslims and Christians held prayers at the square for the victims of the uprising.
Hundreds of thousands of protesters also gathered in the cities of Alexandria and Mansoura, while thousands more protested in Mahalla. In other parts of the country, banks and shops began to reopen as normal life was seen to be resuming.
Egyptian regime’s spokesman Magdi Radi said the parties agreed to form a committee of judges and politicians “to study and propose constitutional amendments and required legislative amendments... by the first week of March.”
Negotiators also agreed to open an office for complaints about the treatment of political prisoners, loosen media curbs, to lift an emergency law “depending on the security situation” and reject foreign interference.
But Suleiman refused another key demand of the opposition, saying he would not assume Mubarak's powers and rule in his stead during the transition.
Not all of the opposition movements involved in the 13-day-old uprising against Mubarak's rule were present at the talks, with former UN nuclear watchdog head Mohamed ElBaradei notably not invited.
ElBaradei told the American television station NBC that he had not been invited to the talks. He slammed the negotiations for being “opaque”, saying that “nobody knows who is talking to whom at this stage”.
However, a representative of ElBaradei was also in attendance.
Other opposition leaders met Suleiman in a palatial government hall under a huge portrait of the absent Mubarak.
Some of the undaunted protesters celebrated Christian prayers in the central Cairo square, the epicenter and symbol of the revolt, to remember the estimated 300 people who have been killed since demonstrations against Mubarak began.
“God bless the dead. God bless the dead,” recited a Christian preacher wearing a crucifix. By his side, a Muslim cleric stood holding a Holy Quran, as the faithful chanted “A single hand. A single hand,” in inter-faith solidarity.
Mubarak has thus far refused demands to step down immediately, insisting that while he is “fed up” with leadership, he feels he must stay on until a promised September presidential election in order to ensure stability.
The crisis has given U.S. President Barack Obama's administration a policy headache, forcing it to confront the consequences of Washington's long-term support for Middle East autocrats in exchange for security guarantees
