Top US general Petraeus: 'No quick success in Afghanistan'

A top US general has warned that military success in Afghanistan is likely to be slower than in Iraq after the troop surge there.

Testifying before the US Congress, Gen David Petraeus said, as in Iraq, the situation in Afghanistan was "likely to get harder before it gets easier".

He also urged lawmakers to "withhold judgment on the success or failure of the strategy in Afghanistan until next December".
