Protesters have gathered in central Cairo for a "one million-man march" as demonstrations against the ruling military council continue into a fourth day.
Around 30,000 demonstrators are currently in Tahrir Square, with more expected to join in the hope of forcing the military to speed up the promised transition to civilian power.
Placing further pressure on Egypt's interim rulers, an Amnesty International report published on Tuesday, said the military had failed “to live up their promises to Egyptians to improve human rights".
It also accused the regime of subjecting women to "horrific" torture at the hands of the Egyptian Army, including electric shock treatments and virginity tests.
The Amnesty report also detailed how violations of human rights rife under Mubarak, including the use of torture and the banning of criticism of the government, have continued under the new regime.
"The euphoria of the uprising has been replaced by fears that one repressive rule has simply been replaced with another," it said.
Three days of clashes between security forces and protesters have left 35 reportedly dead and at least 1,200 injured, while the continued violence has thrown next week’s scheduled elections into doubt.
The demonstrators fear the military leaders, who took control after Mubarak’s fall, intend to hold on to power, regardless of the election results.
On Monday, Egypt’s interim civilian leadership, offered the supreme council of the armed forces (SCAF), their resignation in the hope of quelling the violence. It remains unclear whether the resignations were accepted.
"All I ask of the people is that they leave, calm down,” Prime Minister Essam Sharaf said outside the government headquarters on Tuesday.
Despite the plea, protesters have braved tear gas to assemble in the square.
The head of SCAF, Field Marshal Mohamed Hussein Tantawi, is expected to address the nation on state television on Tuesday evening.
On Monday night, fighting in the streets around Tahrir Square raged, as young men aligned with the anti-government protests battled against security forces near the Ministry of the Interior.
