A suicide car bomb attack near a convoy of international troops in eastern Afghanistan has killed a child and another civilian.

Officials say a NATO soldier and at least three other civilians were wounded in Saturday's attack outside the city of Khost.  They say it was aimed at a convoy of the NATO-led International Security Assistance Force.

In related news, the Pentagon said Friday the U.S. Central Intelligence Agency has transferred a high-level al-Qaida member with close ties to Osama bin Laden to the U.S. military prison at Guantanamo Bay, Cuba.

A Pentagon spokesman said the detainee, an Afghan national identified as Muhammad Rahim, helped prepare caves in Tora Bora - a mountainous region in Afghanistan used by bin Laden to hide as U.S.-led forces ousted the Taliban in 2001.  

The spokesman said Rahim helped bin Laden escape during a U.S. operation to catch the al-Qaida leader.  Rahim also attempted to procure chemicals for a plan to attack coalition forces in Afghanistan.

The South Asian news agency ANI reported in August last year that Rahim had been captured in the Pakistani city Lahore.

A memo from CIA director Michael Hayden released Friday confirmed Rahim was captured in mid-2007.  Hayden said he was then placed in a CIA interrogation program.

No details have been released about where Rahim was being held before this week or whether he has provided interrogators with any information.
