CAIRO: Egypt's Interior Ministry says overnight clashes in Cairo between supporters and opponents of the country's Islamist president have killed at least three people.    

A statement from the ministry early Thursday says there were also 276 people injured in the street battles outside the presidential palace in the city's Heliopolis district, including 35 policemen.

The clashes were the worst violence since Egypt's latest political turmoil erupted on Nov 22 with President Mohammed Morsi assuming near absolute powers.

This is the first time supporters of rival camps have fought each other since last year's uprising that toppled authoritarian ruler Hosni Mubarak.
