ISLAMABAD - The inquiry commission on the May 2 US operation in Abbottabad had shown its dissatisfaction over the credibility of evidences gathered during the probe, says a BBC Urdu report. Report quoted a security official familiar with the investigation as saying that the members of the commission had formed a list of 'important witnesses and conducted lengthy interviews. But, the information gathered from these interviews was not sufficient to establish the facts, the report said.

Justice (r) Javed Iqbal, the chairman of the commission, had said after the formation of the commission that he would also ask the United States government to provide evidences.
