Taliban sneak past Marines in southern Afghanistan

Only a few hundred American troops are policing the southern border of one of Afghanistan's major smuggling areas, leaving open a vast expanse of desert that the Taliban use to shuttle in weapons and fighters from Pakistan.

This dusty hamlet 75 miles (120 kilometers) north of the border in Helmand province was the Taliban's key transit point from Pakistan before the Marines arrived in July. Since then, the Marines have set up a series of patrol bases east and west of Khan Neshin to disrupt the Taliban's supply lines.
