Of the 28 dead across the country, two deaths are thought to have happened in Dokki, and seven more in Ramsis, where some conflict is still ongoing.
Our correspondent says that while many thousands came out to celebrate the October 6 anniversary, the government sees it as an indication of people supporting their legitimacy.
Official celebrations are going on in Tharir Square, attended by Interim President Adly Mansour, Defense Minister Abdel
Fattah Al Sisi, Prime Minister Hazem Al Beblawy, Former Defense Minister
Mohamed Tantawi and Former President Anwar Al Sadat's wife, Gihan Al Sadat.

These figures come from the state news agency, quoting the Health Ministry.
This video, broadcast by the Rassd News Network, reportedly shows security forces and men in plain clothes firing towards protesters.
The footage, published on YouTube today, apparently comes from today's demonstrations in Ramsis, Cairo.
Our correspondent in Tahrir Square says the celebrations, which have been going on throughout the day despite violence elsewhere, are starting to wind down.
She also reports some activity in the Dokki area but that demonstrators are not engaging with the security forces.
This day is one usually reserved for prayers and celebration.
Today, three separate anti-coup protest marches have been trying to get to Tahrir Square but have been hampered by tear gas.
Our special correspondent says that the general public feel that the ongoing turmoil is bad for the image of Egypt and having a negative impact on businesses.
"People believe there will be elections as promised next year. The anti-coup alliance aren't buying that."
One of our correspondents says they are at a makeshift hospital where people are getting treatment for their injuries.
Men at the facility say the injured need to be taken to a proper hospital.
Reporting live now, one of our special correspondents in Egypt says there has been a targeting of journalists in the crowds.
The protesters are not giving up, our correspondent says, despite tight security.
Our correspondent, who we are not naming for security reasons, reports from the protests.
Our correspondent says that there is a determination among the marchers that they have as much right to be in Tahrir Square as those who support the military.
Our correspondent is reporting thousands of military supporters turning out in Tahrir Square to mark the anniversary of the October War, passing through three layers of security to gain entry.
Another correspondent, who is with those marching in opposition of military rule, said the numbers of demonstrators grew as the came closer to Tahrir Square to about 4,000.
The marchers were met about 1.5km from the square by security forces who fired teargas and rounds in to the air to push the crowds back.
Away from the demonstrations in Cairo, and to the violence that continues to blight the Sinai peninsula.
Two armed men killed a policeman in El-Arish, northern Sinai, while army troops fired on a car near the border with Gaza.
At least 10 explosive devices prepared to be remotely detonated were found in the car, according to security officials.
Police have apparently arrested 17 demonstrators in Alexandria, believed to be pro-Morsi.
This comes after they fired teargas into the crowds to disperse the protests.
