Forces loyal to Alassane Ouattara, the UN-backed president-elect in Ivory Coast, are reported to have made significant advances southwards.
His rival Laurent Gbagbo, who contests last year’s election result, has called for a ceasefire.
In Abobo, a poor suburb of Abidjan, young Ouattara supporters are in control – but there is evidence of heavy fighting.
“The day before yesterday, we didn’t sleep. Nor did we yesterday. There were shots everywhere. We must tell Mr Gbagbo that the people are suffering,” said one local woman.
