NEW DELHI: The Union home ministry on Monday issued an advisory to all states asking them to ensure zero tolerance for any attempt to weaken secular fabric and exploit religious sentiments.

The home ministry asked all states to take strictest action as per law against communal elements "without any exception whatsoever".

The advisory comes in the wake of Dadri lynching incident.

While law and order is a state subject, the Union home ministry is concerned over communal incidents including the "unfortunate" Dadri lynching.
