Egyptian soldiers have entered a Cairo mosque where a large number of the supporters of ousted President Mohamed Morsi have taken refuge and been surrounded since last night.Reports say that the Egyptian security forces on Saturday entered Cairo’s Al-Fath Mosque, located on Ramses Square. The forces are said to be negotiating with demonstrators in an attempt to convince them to leave the site. Witnesses say a woman died earlier inside the mosque after inhaling tear gas fired by the security forces. Demonstrators inside the mosque have said that they are afraid of being detained by security forces or attacked by the opponents of the Muslim Brotherhood. On Friday night, the security forces besieged the mosque at the end of another day of violence, which left scores of people dead. Earlier in the day, tens of thousands of Morsi supporters took part in what they called the "Day of Rage" against the army and its handpicked government. The security forces and the opponents of the Brotherhood fired on the supporters of Morsi - the country’s first democratically elected leader - leaving more than 100 people dead and hundreds more injured across the Arab country. The Brotherhood denounced Friday’s killings, saying the coup leaders had "lost their minds" and were devoid of any ethics and moral values. Egypt has seen unrelenting violence since General Abdel Fattah al-Sisi, the head of the Egyptian armed forces, announced on July 3 that Morsi was no longer in office.
