Law enforcement agencies have been put on ‘high alert’ following intelligence reports that terrorists may strike during the Muharram days, Dawn has learnt.

It looks a serious threat as the Home Department of Punjab has directed regional police chiefs to book the suspect terrorists on their watch lists under Anti-Terrorism Act, if they are not found at their listed home addresses.

Police sources said the intelligence was that Tehrik-i-Taliban Pakistan and Al-Qaeda might be planning to target luxury hotels and to release “poison into water tanks”.
