The new commander of foreign forces in Afghanistan, Gen David Petraeus, has said he will not be bound by a 2011 target date to start withdrawing US troops.
Speaking on NBC television, Gen Petraeus said he reserved the right to tell President Obama whether the pull-out date was too early.
He was speaking after US forces endured their deadliest month, July 2010, since the Afghan conflict began in 2001.
