Supporters of President Hosni Mubarak are marching towards Tahrir Square in Cairo, where anti-Mubarak protesters are currently camped.
Several thousand people have gathered along the River Nile's Corniche promenade in support of the embattled president, who on Tuesday announced he would step down at the next elections in September.
The pro-Mubarak protesters, who are just half a kilometre away from Tahrir Square, claim Mr Mubarak has made enough concessions and should be allowed to stay in power.
They claim Egypt has been profitable under the leader's 30-year regime and are angry that anti-Mubarak campaigners have, in effect, shut down the capital with their protests.
The mob is made up of people who have been bussed into the city as part of an organised march and those who have spontaneously joined the crowds.
They are currently located outside the offices of the Arabic news station Al Jazeera, which was taken off air by the president.
Soldiers sat in tanks are observing the demonstrations, but there are currently not enough to cope with any violence that could arise if the two sets of protesters clash.
A line of tanks, with barricades placed in front of them, currently restricts the movements of the pro-Mubarak mob.
