Osama had support system in Pakistan: Donilon

Still,no evidence to indicate that top leadership knew Laden was in Pakistan,said Donlion.

Osama bin Laden 8220;had some sort of support mechanism8221; while operating out of Pakistan for six years,a top White House official has said,even as he reiterated that there is no evidence so far which indicates that the top leadership in the country knew about it.

8220;The fact is that Osama Bin Laden operated out of Abbottabad,Pakistan for six years or so,in an operational role,leading al-Qaeda,in a town 35 miles from Islamabad. It is clear that he had some sort of support mechanism there,8221; said National Security Advisor Tom Donilon in an interview.

8220;I don8217;t think at this point we know all the elements of that support mechanism,and we8217;re still obviously working through that,8221; he added.

But,he said he had not seen evidence that Pakistani 8220;leadership elements8221; had knowledge of bin Laden8217;s presence in Pakistan. 8220;I8217;ve not seen any evidence that the Pakistani leadership elements,neither in the army,military,the intelligence or the political leadership,had foreknowledge of Osama bin Laden8217;s operating in Abbottabad,Pakistan,8221; he said.

8220;But,the fact is that he did operate there for an extended period of time,and that raises a lot of questions,and those questions are being asked in Pakistan,8221; Donilon said.

The National Security Advisor said the US has a tremendous amount of information that was recovered from the Abbottabad compound where bin Laden operated.

From the outset,he said,the Obama administration determined that it would launch an aggressive,focused,relentless effort on al-Qaeda and associated groups to dismantle,disrupt and ultimately defeat them. 8220;With respect to the al-Qaeda8217;s leadership ranks,they8217;ve been decimated. We are going to continue these efforts,and these efforts are focused on al Qaeda Central and South Asia,but also focused on affiliates around the world,number one,8221; he said.

Despite disagreement over a number of issues,Pakistan is a very important counter-terrorism partners for the US,he said. 8220;The Pakistanis and the United States have a complicated relationship and there are going to be frustrations,and there are going to be disagreements. We remained engaged with the Pakistanis for a number of very important reasons related to our national security and I think ultimately their security. They are very important counter-terrorism partners for the United States,8221; Donilon said.

8220;They are very important partners of ours and,we will have frustrations and indeed we8217;ve obviously had an important set of conversations,difficult conversations with the Pakistanis since the raid on the Osama Bin Laden compound in Abbottabad,Pakistan. But we8217;re committed to working through these,8221; Donilon said.
