“l Qaeda confirmed that the US killed its military commander for the ‘Khorasan,’ or Afghanistan and Pakistan, in a drone strike in Waziristan in early 2014. Sufyan al Maghribi, a Moroccan who served as the group’s military chief in Afghanistan and Pakistan, is one of many unknown al Qaeda leaders who ‘work in silence and leave in silence,’ according to a prominent jihadist who reported his death one year ago. Maghribi was also a contributor to the jihadist group’s Vanguards of Khorasan magazine.”
