Article: 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. An official ban was imposed on the groups on 12 January. Later that year, the Saudi born Zayn al-Abidn Muhammed Hasayn Abu Zubaydah was arrested by Pakistani officials during a series of joint U.S.-Pakistan raids. Zubaydah is said to have been a high-ranking al-Qaeda official with the title of operations chief and in charge of running al-Qaeda training camps. Other prominent al-Qaeda members were arrested in the following two years, namely Ramzi bin al-Shibh, who is known to have been a financial backer of al-Qaeda operations, and Khalid Sheikh Mohammed, who at the time of his capture was the third highest-ranking official in al-Qaeda and had been directly in charge of the planning for the 11 September attacks.
