Clashes between Egyptian riot police and protesters stopped overnight for the first time in days on Thursday, though demonstrators occupying Cairo's Tahrir Square vowed to stay put until the army relinquished power.

We want to stop these clashes, people are dying...they are young kids throwing stones at the police, said 30-year-old protester Osama Abu Seree.

In the first significant pause in violence since Saturday, clashes stopped at midnight in Tahrir and elsewhere after protesters agreed with police to stay in the square.

But the thousands who thronged the square were undeterred in their determination to protest at the deaths of more than 30 people in the violence and reject the army's offer of a referendum on its rule.

He goes, we won't, declared one banner in a reference to the head of the military council, Field Marshal Mohamed Hussein Tantawi.

In light of the violence, Interior Minister Mansour el-Essawy presented a report to the military council proposing a postponement of the parliamentary election planned for November 28, Al Jazeera television said on Thursday, quoting unnamed sources. It was not immediately possible to verify the report.

The election, due to begin on Monday, has been billed as Egypt's first free vote in decades.

The army and the Muslim Brotherhood, which expects to do well in the election, says it must go ahead but many protesters are unwilling to trust the army to oversee a clean vote and hand real control of the country to the winner.

The generals' popularity has waned in the nine months since they nudged President Hosni Mubarak from office and swore to steer the country towards civilian democracy, as suspicion grew that they were manoeuvring to stay in power beyond elections.

Tantawi, has pledged to bring forward a presidential vote and offered a new interim government but the demonstrators are unconvinced.

The military council must leave and hand power to civilians. They don't want to leave so that their corruption isn't exposed, said 23-year-old student Ahmed Essam.

He said he joined the protests when he saw riot police raining blows on peaceful demonstrators on Saturday. Everything is like in Mubarak's time, he said.

DEATHS

On Wednesday, Egyptian riot police fired barrages of tear gas at hardcore protesters. Scores of young men, coughing and gasping for air, stumbled into dark side streets off Tahrir Square to escape the acrid smoke during the to-and-fro battle with police.

Gunfire rattled on Wednesday night near the Interior Ministry, a symbol of state authority and target of the protesters. Several gave accounts of people shot dead but these could not immediately be verified.

At a makeshift clinic near Tahrir, doctor Tareq Salem said four people had died there on Wednesday, two from bullet wounds and two from asphyxiation.

He said three volunteer doctors had been killed since the violence began.

They were fresh graduates, he said, splashing his face with saline fluid to counter the effects of the latest barrage of gas. One died of suffocation, the other two of bullet wounds sustained while assessing injuries outside, he said.

Essawy told state television earlier that only tear gas was being fired by the security forces but there were unidentified people shooting from rooftops near Tahrir.

Thousands turned out in the second city of Alexandria and in Port Said. One died and two were injured in Ismailia, a city on the Suez Canal, security sources said.

In Tahrir Square, protesters on Thursday prevented anyone from entering and chanted go back go back. There had been marches in the square since Wednesday afternoon calling for an end to bloodshed.

SURGE OF SOLIDARITY

What started as a sit-in on Saturday night has turned into a mass demonstration reminiscent of the 18-day uprising against Mubarak as Egyptians appalled at the mistreatment of protesters joined them in solidarity.

Youthful demonstrators took Tantawi's offer of a referendum on whether military rule should end earlier as a ploy to undermine their cause by appealing to Egyptians who fear further upheaval.

Many worry the unrest will prolong economic stagnation and delay any improvement in a morose business climate that has deepened the poverty of millions.

Those that did join the protest said it is always better to take a stand.

I want to have a better life and feel safe. Since the military council took power, it has been worse, said protester Abdel Salam Roshdy.

The overall death toll has reached 39 by a Reuters count. One man was killed in Alexandria and another died in what the state news agency MENA said was an attack on a police station in the northern town of Marsa Matrouh.

The Health Ministry said 32 people had been killed and 2,000 wounded in disturbances across the country of 80 million.

Egypt's currency dipped to its lowest level in almost seven years on Wednesday and the yield on an Egyptian dollar bond soared to its highest since March, suggesting that investors are unconvinced that stability will return soon.
