Pakistan has banned NATO supply convoys from entering Afghanistan after fighting between NATO troops and militants led to the killing of three Pakistani soldiers, according to a military official from the NATO-led command in Afghanistan.
The troops were killed when three NATO helicopters crossed from Afghanistan into Pakistani airspace early Thursday and attacked a military outpost, Pakistani security officials said. Three troops were wounded as well, the officials said.
Supply convoys are all-important for the Afghan war effort, and officials from NATO's International Security Assistance Force (ISAF) were trying to
persuade Pakistan to lift the ban. Coalition forces rely heavily on convoys from Pakistan to bring in supplies and gear.
