An office of Ivory Coast opposition leader Alassane Ouattara has been attacked in the main city Abidjan, with unconfirmed reports of several dead. The violence broke out despite a night-time curfew after a deadline to release the results of Sunday's election run-off was missed. Supporters of President Laurent Gbagbo are preventing the results from being released, saying there was fraud in the north, where Mr Ouattara is popular. The election is the first for a decade. It is intended to reunify the country, the world's largest cocoa producer, divided since a 2002 civil war. Former rebels still control the north. There are also unconfirmed reports of continuing clashes between rival political groups. The violence flared in the Yopougon district in the west of Abidjan, seen as a pro-Gbagbo area. Source: BBC
