ABIDJAN, Ivory Coast – Witnesses say security forces fired on protesters for the second consecutive day in Ivory Coast's biggest city, following a call for an "Egypt-style" uprising to depose sitting president Laurent Gbagbo.

The witnesses say military police encircled a group of supporters of Alassane Ouattara in the Abobo district of Abidjan on Sunday afternoon, before opening fire. There were reports of several injured, though their numbers could not be independently verified.

An African Union delegation is due to arrive Monday to attempt to find a resolution to the crisis. Gbagbo is refusing to cede power even though results certified by the United Nations showed Ouattara had won the Nov. 28 election.

Ouattara's prime minister has called on supporters to rise up like in Egypt.
