Egypt presidential candidate Ahmed Shafiq's HQ attacked

The campaign headquarters of Egyptian presidential candidate Ahmed Shafiq has been attacked by protesters.

Egyptian TV stations broadcast footage of a fire at the building, in the Dokki district of the capital Cairo.

There are currently no reports of injuries, and the fire was quickly put out with no signs of serious damage.

The attack comes amid protests against election results hours after it was announced that Mr Shafiq would compete in a run-off next month.

The attackers also took a number of campaign posters and allegedly took a number of computers from the building, the BBC's Jon Leyne reports from Mr Shafiq's HQ in Cairo.

Anti-Shafiq protesters then dispersed and a number of Mr Shafiq's supporters then arrived at the scene, our correspondent adds.

Crowds were also heading to the city's central Tahrir Square, scene of the protests which forced the resignation of President Hosni Mubarak in February 2011 and frequent demonstrations ever since.

It is after midnight and a few young Egyptians are still arriving - taking the familiar route across Qasr al-Nil bridge in the darkness.

They say the presidential election result gave them no choice.

"We aren't at all satisfied with Ahmed Shafiq, who was the prime minister of Mubarak in our revolution. We'll never accept such a guy," said Mustafa Shawat. "The other candidate is the Muslim Brotherhood and we don't agree at all to be in their hands. We want our freedom."

Some protesters have set up a new camp in the middle of this busy roundabout. Yet it remains to be seen how many will stay the night. A shout of "thugs" caused a few moments of panic and a surge of people turned away from the Interior Ministry. With tensions so high there are fears of renewed clashes.

Several hundred people, perhaps as many as a thousand have gathered in the roundabout at the centre of the square, protesting against the official election results, the BBC's Yolande Knell reports from the square.

A steady stream of protesters is continuing to head to the square despite the late hour, our correspondent adds.

Earlier on Monday, Egypt's election commission confirmed that the Muslim Brotherhood's Mohammed Morsi and Mr Shafiq will contest a presidential run-off in June.

Mr Morsi gained 24.3% of the vote in the first round of the poll held last week while Mr Shafiq won 23.3%.

However, there is real anger at the results among many activists, our correspondent says.

Many are saying that they are prepared to stay in the square and that this is the "last chance" too save Egypt's revolution.

Mr Shafiq was the last prime minister to serve under Mr Mubarak and is viewed by many as a representative of the old regime.
