Egypt's opposition movement shifted its strategy Wednesday, calling for a national dialogue to resolve the country's ongoing political crisis days after it had rejected an almost identical invitation from embattled President Mohammed Morsi.

In another reversal, the National Salvation Front, a loose coalition of liberal and secular opposition leaders, held a meeting with the ultraconservative Islamist Nour party, a Salafist group considered far more extreme than Morsi and his Islamist supporters in the Muslim Brotherhood. The liberals had previously denounced the Salafists for espousing of a strict interpretation of Islamic law. The move came six days into a political crisis that has seen dozens killed and more than 1,000 injured in clashes between antigovernment demonstrators and police.
