The US has named a top air force general to head the investigations into the Nato air strike on Pakistani border posts that left 24 soldiers dead and has invited Pakistan and Afghanistan to join the probe.
Brigadier general Stephen Clark from US central command headquarters in Florida has been named to probe the last weekend's incident which has triggered a fury in Pakistan.
Announcing the appointment of the high-level probe, US Central Command (CENTCOM) commander general James Mattis said the governments of Afghanistan and Pakistan would be invited to participate into the investigation.
The investigation team has also been directed to include input and participation from Nato-led International Assistance Security Force (ISAF) in Afghanistan.
US Central Command, which oversees US forces in the Middle East and Afghanistan, said in a statement that the governments of Pakistan and Afghanistan had been asked to join the probe to determine "what happened and preclude it from happening again."
Clark, posted at headquarters Air Force Special Operations Command at Hurlburt Field in Florida, has been asked to provide an initial report by December 23.
The Nato-led ISAF sent an initial assessment team over the weekend to the border to look into the incident.
Pakistan has charged that the air strike was unprovoked, while Afghan and Western officials say that Pakistani forces opened fire first.
