The Gujarat Anti-Terrorism Squad (ATS) on Tuesday said it has arrested three suspected Al-Qaeda operatives from Rajkot. "They were working in gold polishing units in Rajkot," Bhadran said, adding that one of the trio was in touch with a Jamatul Mujahidin Bangladesh (JMB) operative Abdulla Talha, who was arrested by the Bangladeshi counter terrorism agency some days back.
