Sheikh Imran Ali Siddiqi, a senior official in al Qaeda in the Indian Subcontinent (AQIS), was killed in a US drone strike earlier this month. After 9/11, Imran founded Harkat-ul-Mujahideen al-Almi (HUMA), an al Qaeda-linked group thought to be responsible for an attack on the US Consulate in Karachi and other Western interests.
