Diplomatic sources told NPR that Oman's sultan, Qaboos bin Said, paid $500,000 each to free Bauer and Fattal – the same amount paid to liberate Shourd. Oman also provided a private plane to transport the two men to its capital city of Muscat much like it did with Shourd.
The State Department had no immediate comment on Oman's involvement in Wednesday's releases. But when Shourd was freed, department spokesman P.J. Crowley praised Muscat as "a key interlocutor" that helped "work this case with the Iranian government."
