Kabul - Insurgents killed another five US soldiers in Afghanistan's southern Taliban stronghold, NATO said Friday, with their commander poised to request more troops to avoid failure in the eight-year war.

    Two soldiers were killed outright and three later died of their injuries in a trio of separate incidents on Thursday, the NATO-led International Security Assistance Force (ISAF) said Friday.

    "Two members were killed and one died from wounds as a result of an improvised explosive device (IED) detonation," ISAF said, referring to the remote-controlled bombs that have become the scourge of troops in Afghanistan.
