Ahmed Omar Saeed Sheikh (Urdu: احمد عمر سعید شیخ) (sometimes known as Omar Sheikh, Sheikh Omar[1], Sheik Syed[2], or by the alias "Mustafa Muhammad Ahmad"[3]) (b. December 23, 1973) is a British-born militant of Pakistani descent with alleged links to various Islamic-based organisations, including Jaish-e-Mohammed, Al-Qaeda, Harkat-ul-Mujahideen and Taliban.

Pakistani President, Pervez Musharraf, in his book 'In the Line of Fire' stated that Sheikh was originally recruited by British intelligence agency, MI6, while studying at the London School of Economics. He alleges Omar Sheikh was sent to the Balkans by MI6 to engage in jihadi operations. Musharraf later went on to state "At some point, he probably became a rogue or double agent".

In an interview given to David Frost in November 2007, Benazir Bhutto states that Osama bin Laden was killed by Omar Sheikh. Omar Chatriwala, a journalist for Al Jazeera English, claims that he chose not to pursue the story at the time because it was an apparent slip of the tongue. A month before Frost interview, in Oct 2007, Bhutto stated in an interview that she would cooperate with the American military in targeting Osama bin Laden.

So which one is correct? Did Benazir have a 'slip of the tongue' during the Nov. 2007 interview? Or did she perhaps just give lip service in the AP article to gain support from the U.S.?
