Egypt's public prosecutor ordered on Monday the detention of deposed President Mohamed Morsi for 15 days pending an investigation into allegations he participated in "violent acts", state news agency MENA said.
On Thursday, Egyptian judicial authorities extended Morsi's detention period for 30 days in a separate case.
Morsi, who was overthrown by the army on July 3, is being held at an undisclosed location on allegations of murder and spying. The new case centers on protests that took place in front of the presidential palace last December, MENA said.
Worldwide protests in support of Egypt
Meanwhile, humanitarian groups around the world held protests on Monday to call for an end to the violence and bloodshed in Egypt.
About a thousand Indonesians rallied in the capital, Jakarta, denouncing violence by Egyptian security forces that has killed hundreds of civilian supporters of ousted President Mohammed Morsi.
The National Committee for Humanitarian and Egypt Democracy called on the Indonesian government as well as the international community and human rights groups to help stop the bloodshed, which has killed almost a thousand people on both sides.
They protesters rallied at the Hotel Indonesia traffic circle before marching to the Egyptian Embassy.
Some also waved placards supporting Morsi.
Similar protests condemning the violence in Egypt have been held in Jakarta and other cities across the world's most populous Muslim country this week.
Meanwhile, Thai nationals living in Egypt were greeted by relatives at Bangkok international airport on Monday, having chosen to leave Cairo in the face of worsening political violence.
Similarly, Amnesty International leaders met in the German capital, Berlin, on Monday to voice their concerns about violations of basic human rights in Egypt.
Hosni Mubarak:
This as Hosni Mubarak, the former Egyptian president overthrown in an uprising in 2011, will be released from jail in the next 48 hours after a prosecutor cleared him in a corruption case, his lawyer Fareed El-Deeb told Reuters.
He was speaking after judicial authorities ordered Mubarak released in one of the remaining corruption cases against him.
The only legal grounds for Mubarak's continued detention rest on another corruption case which will be cleared up later this week, Deeb said.
"All we have left is a simple administrative procedure that should take no more than 48 hours. He should be freed by the end of the week," Deeb said.
Mubarak, 85, still faces a retrial on charges of complicity in the murder of protesters during the 2011 revolt.
Saudi Arabia's aid to Egypt:
Meanwhile, Saudi Foreign Minister Prince Saud al-Faisal pledged to fill any financial gaps left by Western countries withdrawing aid from Egypt over its crackdown on Muslim Brotherhood protesters that has left hundreds dead since last week.
"To those who had declared they are stopping aid to Egypt or are waving such a threat, the Arab and Muslim nations are wealthy with their people and resources and will not shy away from offering a helping hand to Egypt," he told state news agency SPA.
International Positions:
Earlier, the European Union is set to hold a first round of emergency talks on the "extremely worrying" bloodshed taking place in Egypt amid warnings launched by the union saying it will "urgently review" its ties with the violence-wracked country.
Ambassadors on the EU's political and security committee were called from their summer break to meet in Brussels on Monday after the death toll from five days of violence in Egypt climbed to almost 800.
In this context, the presidents of the European Council and European Commission said on the eve of the talks that the 28-nation union was ready to review its relations with Cairo, warning against the “unpredictable consequences” on Egypt and its neighboring countries that could result from further escalation.
However, members of Congress are split over whether the US should cut off military aid to Egypt, highlighting the difficult choices facing the Obama administration amid spiraling violence on the streets of an important Middle East ally.
Democratic leaders have generally supported the president's approach. But on Sunday, Democratic Congressman Keith Ellison said he would end aid to Egypt. Ellison is the first Muslim elected to Congress and is co-chairman of the Congressional Progressive Caucus.
National Security Council spokeswoman Caitlin Hayden said funding for Egypt remains under review.
Among Republicans, there were growing calls to eliminate military aid to Egypt. But others were more hesitant.
On the field:
Elsewhere, Egyptian security officials say suspected militants have ambushed two police minibuses in northern Sinai, firing rocket-propelled grenades and killing 24 policemen.
The officials say the Monday morning attack took place as the two vehicles were driving through a village near the border town of Rafah in the volatile Sinai Peninsula.
They say the attack also left three policemen wounded. The officials spoke on condition of anonymity as they were not authorized to talk to the media.
Sinai has been witnessing almost daily attacks by suspected militants since the July 3 ouster of Islamist President Mohammed Morsi in a military coup.
On another note, relatives of 36 prisoners killed in clashes involving Egyptian security forces visited a morgue in Cairo, seeking further information about their family members' deaths.
The suspects killed were part of a prison-truck convoy of some 600 detainees heading to Abu Zaabal prison in northern Egypt, security officials told The Associated Press.
Detainees in one of the trucks rioted and managed to capture a police officer inside, the officials said.
Security forces fired tear gas into the truck in hopes of freeing the badly beaten officer, the officials added.
The officials said those killed died from suffocating on the gas.
The officials spoke on condition of anonymity because they were not authorized to speak to journalists.
However, the officials' version of events contradicted reports about the incident carried by state media.
The official website of Egyptian state television reported that the deaths took place after security forces clashed with militants near the prison and that detainees came under fire while trying to escape.
The official MENA state news agency also said the trucks came under attack from gunmen.
