A video showing two Egyptian activists writing graffiti inciting the population to stand up against the ruling military council has gone viral on social media sites.

The footage, which appeared on sites such as YouTube and Twitter, shows two activists from the protest group Zan Zans 25 wearing Guy Fawkes masks similar to those worn by members of the Occupy movement, as they run through the streets of the Zamalek district of central Cairo, dancing and writing graffiti calling on Egyptians to march against military rule in the country.

Activists and opposition political parties are urging people to turn out for a mass rally on 25 January to continue pressure on the authorities to satisfy the demands made at the start of the revolution that toppled former president Hosni Mubarak.

"We did the graffiti because we want the people in the streets to know what's happening outside national TV, which is misleading," a member of Zan Zans 25 exclusively told International Business Times UK.

"We danced to show that our determination will never be swayed and that we will continue to criticise with joy. There is no revolution without dancing and joy."

The graffiti at the end of the video reproduces the lyrics of the background song by the Egyptian band the Choir Project, which read: "The Revolution, who stole it? Who controls its media? Who is putting civilians on trial in military tribunes? Who is calling us thugs? Where is the tank? Who is driving it? Who ran us over? Who is making our state worse by the minute? Who is making us hungry? Who is killing our joy? Who is trying to frighten us? The Supreme Council of the Armed Forces, that's who."

The activists stressed that they are not part of either the Anonymous or Occupy movements.

"We are independent," they said. "A year ago we took to the streets and chanted 'Bread, freedom, social justice'. After a year, absolutely nothing changed. Our situation has become worse than before. So we will go to the streets again and the regime will fall once and for all."

In December, a hacker cell from Anonymous pledged to renew its campaign in Egypt after footage emerged showing members of the Egyptian armed forcessavagely beating a female protester.

A slew of reports then appeared on the internet reporting that websites operated by the Egyptian government were going offline, prompting speculation that Anonymous had carried out another series of attacks on the sites to protest against the brutality of the armed forces.

In addition to Anonymous' support for the revolution, its denial-of-service attacks are believed to be part of the collective's links to the Occupy movement, whose followers participated in demonstrations in Tahrir Square in Cairo.

Zan Zan 25's video was uploaded after Egyptian police arrested four activists for putting up posters criticising the ruling military council's heavy-handed tactics against female protesters.

Those activists were from the April 6 Youth Movement, which helped trigger the uprising that ousted President Hosni Mubarak in February.
