UPDATE 3/18 11:53 AM: Here are two more videos that were released:
NOTE: Muḥammad aẓ-Ẓawāhirī is Ayman aẓ-Ẓawāhirī’s younger brother. In 1981 Muḥammad was indicted in absentia for the assassination of Egyptian President Anwar as-Sādāt after Ayman implicated him in recruiting members to Tanẓīm al-Jihād while living in Saudi Arabia. He was found not guilty. He then lived in Yemen and then moved to Sudan in the 1990s to meet up with his brother and the al-Jihād organization. Following the expulsion of jihādīs in 1996, Muḥammad returned with his family to Yemen. He worked as an engineer contractor and traveled to the United Arab Emirates (UAE) frequently for work. He was once again brought up on charges in absentia, this time in connection with the Returnees from Albania trial and he was convicted. As a result, he was arrested in the UAE in March or April 1999 and renditioned to Egypt. He was sentenced to death, but since then he has been held at the infamous Tora prison run by the Egyptian security services. Two years later, he is now free. Should be interesting to see what he says and does next as well as if Ayman releases a new audio message about it.
