Pakistani intelligence officials are tracing links between Times Square bombing plot suspect Faisal Shahzad and banned terror group Jaish-e-Muhammad, led by Maulana Masood Azhar. This search has led investigators to the sprawling, marble-floored Batha Mosque and a religious school in a crowded neighbourhood of Karachi, which was once the provincial headquarters of the JeM and was visited by the elusive Azhar, who was released from prison in 1999.
