CAIRO — A senior Egyptian health official says overnight clashes between supporters and opponents of the country's ousted president near Cairo's main university have left six dead.

Khaled el-Khateeb, who heads the Health Ministry's emergency and intensive care department, said the six died early Tuesday close to the site of a sit-in by supporters of Mohammed Morsi.

The military ousted Morsi on July 3 following days of massive street protests by millions of Egyptians demanding that the Islamist president step down. His supporters are calling for his reinstatement and insist they will not join the military-backed political process until then.
