Alaa, Gamal Mubarak, sons of former Egyptian leader, released from prison

The two sons of ousted Egyptian President Hosni Mubarak were released from prison Monday, nearly four years after they were first arrested along with their father, authorities said.

Security officials said the two, wealthy businessman Alaa and Mubarak's one-time heir apparent Gamal, walked free from Torah Prison in a southern Cairo suburb shortly after daybreak and headed to their respective homes in the capital's upscale Heliopolis suburb.

The two, along with their father, still face a retrial on corruption charges. Separately, the two sons also face trial on insider trading charges. They had been acquitted of other charges.

Mubarak, now 86, stepped down in February 2011 in the face of a popular uprising. He and his two sons were arrested in April that year. Mubarak remains held at a military hospital in a southern suburb of Cairo.

The security officials spoke on condition of anonymity as they weren't authorized to speak to journalists.

The release of the two had been expected for several days. However, it comes a day after deadly clashes between anti-government protesters and police marked the fourth anniversary of the uprising that ended their father's 29-year rule. That violence Sunday left at least 18 people dead, including two men authorities said died planting a bomb and three police officers, and dozens wounded. The release of Mubarak's sons could spark further demonstrations.

The two, particularly Gamal, are viewed by many Egyptians as among the pillars of an authoritarian and corrupt administration that struck an alliance with mega-wealthy businessmen at the expense of the nation's poor and disadvantaged.

Mubarak was widely believed to have been grooming Gamal to succeed him. The two consistently denied that, but the perceived succession plan, along with corruption, police brutality and poverty, were among the main causes of the 2011 uprising.
