Egyptian police fire tear gas at protesters

Egyptian police have fired tear gas into Tahrir Square in Cairo after a night during which several hundred people remained to show their anger at a decree issued by President Mohammed Mursi giving himself extensive new powers.

On Tuesday, tens of thousands of demonstrators streamed into the square, holding a variety of marches and chanting slogans denouncing the president and his main group of supporters, the Muslim Brotherhood.
