He rose in rank by participating in the creation of the GSPC in 1998. In November 2009, Youssef narrowly escaped death when he fell into an ambush by the Algerian army in the maquis of Imsouhel, in the wilaya of Tizi Ouzou.[4]
After the death of Abdelmalek Droukdel, AQIM announced on 21 November 2020 that Abu Ubaidah Youssef al-Annabi had been appointed to succeed him.[5]
On 29 September 2015, the U.S. State Department designated al-Annabi as a Specially Designated Global Terrorist under Executive Order (E.O.) 13224.[6]
On 28 March 2023, the government of Burkina Faso suspended the broadcasting of French state-owned media France 24 after they aired an interview with al-Annabi. The country's information minister at the time, Jean Emmanuel Ouédraogo, described the channel as, "not only acting as a mouthpiece for these terrorists but worse".[7]
