US President George W Bush has urged NATO allies to send more troops to Afghanistan.
He says the alliance could not afford to lose its battle against Taliban insurgents and al-Qaeda militants.
In a keynote speech before a summit of the 26-nation defence alliance in the Romanian capital, Bucharest, President Bush said whatever the cost, however difficult, 'we must win'.
NATO allies want the Bucharest summit today to send the message that its 47,000-strong peacekeeping force will stay in Afghanistan for as long as necessary to battle the insurgency.
French Prime Minister François Fillon said yesterday that Paris was looking to send several hundred more troops to Afghanistan.
That was far short of the 1,000 extra soldiers that some NATO allies had been expecting and it was not clear whether it would be enough to cover a Canadian demand for reinforcements in the south.
Canada has said it could pull its 2,500 troops out of the fight next year if the reinforcements were not forthcoming.
