UPDATE: We have our answer. BBC was right and NYT was wrong. On 31 August a correction appeared here stating that Abdelhakim Belhaj and Abdel Hakim al-Hasad are two different people.

Abdelhakim Belhaj (also known as Abdel Hakim al-Hasadi and Abu Abdullah al-Sadiq) is the former commander of the Libyan Islamic Fighting Group (LIFG), currently called the Islamic Movement for Change. According to NYT, Abdelhakim Belhaj is the same person as Abdel Hakim al-Hasadi. According to BBC, Abdelhakim Belhaj is the same person as Abu Abdullah al-Sadiq. Who is right?
