Kabul-Kandahar Highway Blocked by Taliban

Taliban fighters block major Afghan highway in expanding attacks - The Boston Globe: 

The highway attack about 30 miles west of Kabul was the latest assault by Taliban insurgents on provincial centers. The militants have also threatened cities in the north, northwest, and south.
A spokesman for the provincial governor, speaking to the Reuters news agency, said fighting continued just outside the town. Any break in Afghanistan’s main highway is a serious blow, since it carries nearly all commerce and supplies, and alternative routes are extremely difficult.
