French and UN helicopters have fired on military camps operated by Ivory Coast incumbent leader Laurent Gbagbo, in a bid to halt attacks on civilians. The strikes came as fighters backing Mr Gbagbo's rival Alassane Ouattara stepped up their attempts to take control of the main city, Abidjan. The UN has been under pressure to fulfil its mandate to protect civilians, and asked for French help. International groups say Mr Ouattara is the legitimate leader of the country. Observers and regional bodies say he won elections late last year, but Mr Gbagbo has refused to step down.
