Belmoktar, the al-Qaida leader behind the attack on a remote natural gas plant in Algeria in January that killed 37 foreign workers, is seen in the video released online late Tuesday, CBS News reported.
In the video, he is training other militants and is seen bidding farewell to suicide bombers who carried out an attack on a French petroleum company in northern Mali in May.
He is also seen speaking to another prominent jihadist, Abdel Hamid Abou Zaid, who is also said to have died earlier this year.
Belmoktar joined the Armed Islamic Group in 1993 and later worked with al-Qaida before splitting with it to create his own group, the Signatories with their Blood.
In the January attack, Belmoktar and other members of his group took 800 workers hostage at the gas production facility.
The four-day standoff ended when Algerian forces stormed the complex.
Thirty-seven workers, one Algerian security guard and 29 militants were killed.
