Geneva/Cairo: Egyptian Nobel Peace Prize winner Mohammad Al Baradei is to face trial on September 19 over his resignation as vice president after a deadly crackdown on the Muslim Brotherhood, state-run newspaper Al Ahram reported online on Tuesday.

The case against him was brought by the head of criminal law in Helwan University, who argues that Al Baradei was appointed vice president as a representative of the opposition and was obliged to refer his resignation to them.

Al Baradei left Cairo for Vienna on Sunday, according to Al Ahram.

Meanwhile, the UN rights office said Tuesday that it was pressing Egyptian authorities to let it deploy monitors in the crisis-wracked country.

Spokeswoman Liz Throssell told reporters that the office was seeking a green light to send “several” human rights observers to assess the situation.

“We’re calling to have human rights officers allowed on the ground in Egypt so they can gather information, they can talk to NGOs, national human rights institutions, draw up reports,” she added.

Last Thursday, UN rights chief Navi Pillay demanded an “independent, impartial and credible” probe into the bloody crackdown by Egypt’s security forces, saying anyone found guilty of wrongdoing should be held to account.

According to Egyptian authorities, hundreds of people were killed in last Wednesday’s assaults on two Cairo protest camps of supporters of ousted Islamist president Mohammad Mursi in the country’s worst violence in decades.

The Muslim Brotherhood has put the death toll at over 2,000.

Throssell said that Egypt’s UN ambassador had held talks with senior human rights officials in Geneva the day Pillay made her appeal, and had informed them that a probe had been launched.

Since then, the UN has also called for an investigation into the deaths of three dozen Islamist detainees in police custody, and condemned a militant ambush of police buses in Egypt’s Sinai Peninsula on Monday that left 25 policemen dead.

“We remain alarmed at the continuing violence in Egypt,” said Throssell of the Office of the High Commissioner for Human Rights.

With hundreds of Muslim Brotherhood members, including senior leaders, caught up in the security forces’ dragnet, Throssell also said Egypt’s treatment of detainees was under watch.

“Everyone deprived of liberty must be treated humanely and afforded all judicial guarantees under international law,” she said.

The Egyptian armed forces Tuesday arrested 11 people, including two Palestinians, in Sinai over attacks on the police and army premises.

The forces raided several criminal hideouts early Tuesday morning and arrested them.

The operation came one day after suspected militants ambushed two buses carrying security forces in Egypt’s northern Sinai, killing at least 25 soldiers.

The security condition deteriorated in Sinai since the ouster of former president Hosni Mubarak in 2011, and became worse after his successor Mohammad Mursi’s government was toppled, which triggered violence between security forces and Mursi’s supporters.
