NATO general says Pakistan chaos emboldens Taliban

U.S. Gen. David D. McKiernan, who took over the NATO command in Afghanistan in June, said attacks have spiked this year. McKiernan said the insurgency is drawing its strength from a "deterioration of conditions across the border in Pakistan."

"Militant sanctuaries are expanding in the tribal areas," McKiernan told The Associated Press on Monday. He said insurgents are mustering larger forces against international troops and carrying out more roadside bombings, suicide attacks and ambushes.

The U.S. and NATO are concerned the weak hold Pakistan's new government has on the tribal region, where they fear cease-fire deals have allowed militants based in the frontier areas to step up attacks across the border in Afghanistan and plot attacks on the West.

McKiernan, who described the insurgency as "resilient," said the most violent attacks come near the Pakistani border and are often connected to Afghanistan's ring road that links the country's major cities.

Earlier this week, militants ambushed a group of French soldiers, killing 10 in a gorge just 20 miles outside the capital, Kabul.

And in a July attack that left nine American troops dead, upwards of 200 insurgents ambushed U.S. soldiers in a mountainous region that borders two Pakistani districts so troublesome that Pakistan was forced to send in troops this month despite the government's attempts at a truce.

Over the past several months McKiernan said NATO has seen an influx of Chechens, Turks and Middle Eastern fighters as well as "sometimes Europeans."

Some are coming through Iran and others are getting off international flights at Pakistan's southern port city of Karachi before heading northwest to training camps in the border regions. Worrying to McKiernan is the increased ease with which insurgents operate in the border areas and their unhindered forays into Afghanistan.

The four-star U.S. general, who commands the 53,000-strong International Security Assistance Force, said soldiers are operating in a complex environment battling a resilient insurgency.
