They said, the situation in the affected areas in Punjab, including<br/><br/>Moga, Bhatinda and Sangrur districts, is tense but under control. Patrolling has been intensified while security has been beefed up at public places like railway stations, bus stations and shopping malls. <br/><br/> Resenting the filing of a murder case against Dera Sacha Sauda head Gurmeet Ram Rahim Singh by the CBI, sect supporters last evening went on a rampage. They set ablaze some trains and vehicles, including 27 buses, and vandalised property in several places in Punjab and Haryana.
