Abidjan resident: We heard bombing

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.

Speaking to the BBC by phone from Abidjan, one resident described hearing bombing and said his house was shaken by the impact.
