14 people have died in the latest clashes between protesters and security forces in Cairo.

The violence, which began on 16 December in the streets around the central Tahrir Square, continues four days later. Up to 1,000 protesters called for the resignation of Field Marshal Mohamed Hussein Tantawi, chairman of the ruling Supreme Council of the Armed Forces (SCAF) and former defence minister in the government of Hosni Mubarak, who was ousted as leader of Egypt in a popular revolution in February.

The health ministry said that over 500 people have been wounded in the clashes, of which 384 have been admitted to hospital. Graphic footage showing soldiers in riot gear kicking and beating a woman, whose partially-removed veil revealed her underwear, has sparked outrage among the protesters.

Most of the deaths happened in the early hours between 16 and 17 December, and an army source was quoted as saying that 164 people had been detained. A research centre housing historic archives on nearby Sheik Rehan Street
