Al-Jazeera Video: Violence flares near Tahrir after tentative ceasfire

"There has been little respite in the streets around Tahrir Square since violence began on Saturday. Central Security Force riot police continue to fight running battles with groups of young men on the front lines, firing tear gas and cartridge rounds against the protesters' rocks and petrol bombs.

A brief cease fire brokered by religious scholars from al-Azhar University brought a short lull to the fighting on Wednesday afternoon, and army soldiers moved in to separate the two sides, backed by armoured personnel carriers.

But the ceasefire was shattered when riot police fired a barrage of tear gas over the soldiers' heads, throwing Mohamed Mahmoud Street - the focal point of the fighting - into chaos.
