KABUL (AP) ― The Taliban published a video Monday they say shows insurgents preparing for the brazen attack on a major NATO base earlier this month, just as NATO forces released data showing that insurgent attacks decreased in August.

The twin releases are a reminder of the escalating battle for public opinion between the insurgency and the international military as U.S. and allied troops draw down. The Taliban continue to contend that they are fighting at full force while the international alliance says that they have been weakened.

In the Sept. 14 attack on Camp Bastion in Helmand province, 15 insurgents dressed in U.S. Army uniforms breached the base’s perimeter fence then used automatic rifles and rocket-propelled grenade launchers to fire on planes and people around the base’s airstrip.
