Global jihadi network al-Qaeda on Thursday officially announced the establishment of its unit in Jammu and Kashmir, naming former Hizbul Mujahideen militant Zakir Musa as its chief in the state. While Musa is said to be a close aide of slain Hizbul Mujahideen commander Burhan Wani, the new cell has been named Ansar Ghawzat-ul-Hind.
