Afghanistan ? A top American general said Sunday that attacks along the Afghan-Pakistan border have dropped more than 40 percent since July and the U.S. and its allies are making progress in the fight against the Taliban.

Brig. Gen. Joseph Votel said the decrease in insurgent activity along the border could be attributed to the onset of winter, a rise in insurgent attacks in Pakistan and an increase in communication and coordination among NATO, Afghan and Pakistani forces.

Recent media and analysts’ reports have said the international mission is not succeeding and Afghanistan is becoming increasingly unstable. This year has been the deadliest since the 2001 U.S.-led invasion, with more than 6,300 people killed in the violence, mostly militants.

But Votel, the deputy commanding general of U.S. troops in Afghanistan, said Sunday that the international mission is making progress.
