American military successes in Iraq have prompted growing numbers of well-trained "foreign fighters" to join the insurgency in Afghanistan instead, the Afghan defense minister said on Tuesday.
The minister, Gen. Abdul Rahim Wardak, said at a news conference that the increased flow of insurgents from outside Afghanistan had contributed to the heightened intensity of the fighting here this year, which he described as the "worst" since the American-led forces toppled the Taliban government in 2001. American commanders have said that overall violence here has increased by 30 percent in the past year and have called for more troops.
