Nato's secretary general has said member countries will do substantially more to contribute to the fight against al-Qaeda and the Taliban in Afghanistan. Anders Fogh Rasmussen said non-US Nato countries would provide at least 5,000 extra troops in 2010, and probably a few thousand on top of that. He clarified that this number was in addition to the more than 38,000 already there. Mr. Rasmussen said Nato troops would remain there as long as required.
