KABUL, Afghanistan -- The U.S. military commander in Afghanistan says the killing of Usama bin Laden may weaken Al Qaeda's influence on the Taliban.

But Gen. David Petraeus warns Afghanistan is still a center of international terror groups, and Al Qaeda is just one of them.

Interviewed by The Associated Press, Petraeus said the strong link between Al Qaeda and the Taliban was forged in the basis of relations between the leaders of the groups. Now that bin Laden is dead, that bond could be weakened.

Petraeus said Sunday that the key of the NATO and U.S. strategy in the country has to be making sure that there are no safe havens for these international terrorist groups. He said the terror groups pose a major threat to the country's stability.
