New Delhi, Sep 04 (ANI): Security Expert Alok Bansal on Thursday called for strict action by intelligence agencies in the wake of a video released by Al Qaeda. In a 55-minute video posted online, Al Qaeda leader Ayman al Zawahri, also renewed a longstanding vow of loyalty to Afghan Taliban leader Mullah Omar, in an apparent snub to the Islamic State armed group challenging al Qaeda for leadership of transnational Islamist militancy. Zawahri described the formation of "Al Qaeda in the Indian Subcontinent" as a glad tidings for Muslims "in Burma, Bangladesh, Assam, Gujarat, Ahmedabad, and Kashmir" and said the new wing would rescue Muslims there from injustice and oppression.
