Egypt’s military-installed interim president, Adly Mansour,  is to address the nation after the health ministry announced that 29 people were killed during rival rallies on Saturday’s anniversary of the 2011 uprising.
Among the dead, 26 people were killed during clashes in and around Cairo , amid battles between Islamists and anti-government protesters fought with police and civilian opponents.
Tear gas was fired by police at supporters of ousted Islamist President Mohammad Morsi and other anti-government activists as the country marked the third anniversary of the 2011 uprising that toppled former President Hosni Mubarak. 
Security sources told Al Arabiya News Channel that at least 33 Muslim Brotherhood supporters had been arrested in Cairo for attacking police forces.
Police broke up protests shortly after they began around a Cairo mosque, according to an AFP correspondent.
The protesters included both Islamist supporters of Mursi and activists who accuse Egypt’s army of hijacking the government.
Security forces lobbed teargas and fired in the air to try to prevent demonstrators opposed to the government from reaching Tahrir Square, the symbolic heart of the 2011 uprising that toppled the former air force commander. 
Instead of commemorating Mubarak’s overthrow, a large number of Egyptians gathered in Tahrir to pledge their support for the army chief who ousted the country’s first freely-elected president last year.
The chanting for General Abdel Fatah Al Sisi underscored the prevailing desire for a decisive military man they count on to end the political turmoil that has gripped Egypt since the 2011 Arab Spring revolution and crippled the economy.
Earlier on Saturday, two bomb blasts were reported in Cairo on Saturday as Egyptians marked the third anniversary of their Jan. 25, 2011 uprising.
One bomb exploded near a police academy in Cairo,  wounding one person, security sources said.
The blast was sparked by what was described as a small “incendiary bomb” lodged on the wall of the police training center and exploded without causing any casualties, a police official told Agence France-Presse. It was thrown by an assailant, who later escaped, the official added.
The second blast was reported in Hadaeq Al Quba, a Cairo district. Details of this attack remained unclear.
Later in the afternoon, a car bomb struck a police base in the Egyptian canal city of Suez on Saturday, wounding at least four people in an attack earlier blamed on a rocket.
The booby-trapped car exploded on a street next to the base, General Abdel Fattah Othman  told the private ONTV television. A police spokesman had earlier said a rocket caused the explosion.
The attacks came a day after a series of bombings in Cairo and clashes across the country left at least six people dead and wounded several others. In the most high-profile attack on Friday, a car bomb exploded at a security compound in central Cairo early in the morning and killed at least four people, including three policemen, security sources said.
