Learnt about this Wikileak via Angry Arab blog:
“...On March 28, CDA spoke with President Saleh (who was attending the Arab League summit in Riyadh) via telephone and confirmed that the aircraft belonged to the US Navy. He assured Saleh that the plane crashed performing routine reconnaissance near the ship and had not been operating in Yemeni territory...
“...Comment: President Saleh clearly believes the unmanned aircraft had been performing reconnaissance in Yemeni territory when it crashed. He could have taken the opportunity to score political points by appearing tough in public against the United States, but chose instead to blame Iran...Saleh decided he would benefit more from painting Iran as the bad guy in this case.”
