Violent clashes in Egypt that have left at least 20 people dead continue on Monday morning. About 4000 protesters are in Tahrir Square, according to Al-Masry Al-Youm's correspondent there. Police are still firing rounds of tear gas. Earlier in the morning there was news about a ceasefire in the square, but the situation there remains chaotic, the correspondent says. At a field hospital in the Omar Makram mosque, Ahmad Sami, a volunteer doctor with the Tahrir Doctors Organization, said he saw six cases of people shot with live ammunition. Most cases, he told Al-Masry Al-Youm, are of injuries caused by shotgun pellets. Cases of asphyxiation by tear gas, he said, are more severe than usual. A makeshift hospital was set up in an alley off Mohamed Mahmoud Street, where most of the fighting has taken place, but was repeatedly attacked with tear gas all night. The Ministry of Health put the death toll at 20 this morning, and scores are wounded.
