Egypt PM Essam Sharaf urges calm after Cairo clashes

Egypt's PM has appealed for calm after 24 people were killed as clashes between Coptic Christians and security forces escalated into full-scale riots.

The violence broke out after a protest in Cairo against an attack on a church in Aswan province last week, with Muslims joining in on both sides.
PM Essam Sharaf said discord between Muslims and Christians in Egypt was "a threat to the country's security".
An emergency cabinet meeting has been called for Monday.
The BBC's Yolande Knell in Cairo says there is pressure on ministers and on the country's military rulers to give assurances about national unity.
A nighttime curfew was lifted at 07:00 local time (05:00 GMT).
Mr Sharaf, who toured the area where the clashes occurred, also addressed calls by protesters for the removal of the military rulers.
"The most serious threat to the country's security is tampering with national unity, and the stirring of discord between Muslim and Christian sons of Egypt," he said in a televised address late on Sunday.
