I want to know the answer to the following question:
What group did Maulana Masood Azhar lead?
All the background I'm provided with is that "In 2002, the Musharraf-led government took a firm stand against the jihadi organizations and groups promoting extremism, and arrested Maulana Masood Azhar, head of the Jaish-e-Mohammed, and Hafiz Muhammad Saeed, chief of the Lashkar-e-Taiba, and took dozens of activists into custody.". Is that enough to answer the question?
