Banned terror outfit Indian Mujahideen planned a nuclear attack on Surat and warmed up to the Al-Qaeda and Taliban in Afghanistan to intensify 'jihad' against India. The revelations were made in the National Investigation Agency's supplementary charge sheet filed in a special court here. The agency is investigating charges against IM co-founder Yasin Bhatkal, IM cadre Asadullah Akhtar, Manzer Imam and Ujjair Ahmed, arrested for their alleged role in launching terror strikes across India.
