CAIRO, Dec 5 (Aswat Masriya) - Ten protesters were arrested in the vicinity of Abdel Moneim Riad Square in downtown Cairo amid skirmishes with security forces while attempting to enter the nearby Tahrir Square to stage a demonstration on Friday.

Security forces closed all entrances to Tahrir Square on Friday in anticipation of protests against the acquittal of former President Hosni Mubarak.

A group of political and youth movements have called for peaceful protests against the verdict in squares across Egypt, in a what it called a "revolutionary week".

Hisham Lotfy, a security official, told Aswat Masriya that the 10 protesters were arrested for attempting to "forcibly enter Tahrir Square." He added that they would be released after examination, if they are not wanted for other charges.

A policeman was injured in clashes between security forces and protesters in Abdel Moneim Riad Square, said Health Ministry Spokesman Hossam Abdel Ghaffar.

The Revolutionary Socialists movement announced on its official facebook page on Friday night the cancellation of all its planned events due to "transforming downtown Cairo and all areas of assembly to military barracks."

The pro-Mohamed Mursi Anti-Coup Alliance meanwhile announced Friday the start of a "week of retribution and alignment," calling on political movements to protest for the retrial of Mubarak-era figures.

The Cairo Criminal Court dropped last Saturday the charges against Mubarak and acquitted his Interior Minister Habib al-Adly and six of the latter's aides over complicity in the murder of protesters during the January 2011 uprising which toppled his regime.

The verdict sparked wide dissent and prompted nationwide protests, specifically among university students.

Two protesters demonstrating against the verdict were killed, and 14 others were injured Saturday evening in clashes with police forces in Abdel Moniem Riad Square, the ministry of health said.

Mubarak and his interior minister were sentenced to life in prison in 2012 for the same charges before an appeals court ordered their retrial. The retrial began in April, 2013.

In May, a Cairo court sentenced Mubarak to three years in prison on embezzlement charges.
He is serving time in a military hospital in Cairo, where he returned upon Saturday's ruling.
