Al Qaeda agitated for Sheikh Omar Abdel Rahman’s release from a US prison for more than 20 years. Rahman, whose teachings had a significant influence on al Qaeda’s development, was convicted in 1995 of conspiring to attack several New York City landmarks.

The US killed Rifai Ahmed Taha Musa in an airstrike this week. Musa first began working with Osama bin Laden and Ayman al Zawahiri in the 1980s and 1990s. US intelligence officials identified him as a key figure in al Qaeda’s so-called “Khorasan Group.” According to one of his former comrades, he was in Syria to promote unity between Al Nusrah Front and Ahrar al Sham.
