(CNN) -- The man believed to be the suicide bomber who killed seven CIA employees and contractors last month appears in a newly released video, in which he vows revenge for the killing of a Taliban leader. The video shows Humam Khalil Abu-Mulal al-Balawi, whom a former U.S. intelligence official identified as the suicide bomber. Al-Balawi's brother told CNN Senior International Correspondent Nic Robertson that the man in the video, who uses the alias Abu Dajana Al-Khorasani, was his sibling. In the tape, which aired Saturday on the Arabic satellite news channel Al-Jazeera, al-Balawi says his message is for the CIA and Jordanian intelligence.
