MUMBAI: After facing a blackout in Ahmedabad for showing the Tehelka sting expose, the seven news channels are back on air since late Saturday.

Aaj Tak, NDTV India, NDTV 24X7, IBN7, CNN-IBN, Tez and Headlines Today were put off air since 26 October.

Cable operators were ordered by the District Collector of the city, Dhananjay Dwivedi, to put the channels off air, following Tehelka's 'Operation Kalank' sting expose of the Gujarat riots.

Dwivedi, who is also the District Election Officer, on 26 October issued an order to all cable television operators not to telecast the Tehelka expose of the Gujarat riots "Operation Kalank."

The Friday order quoted the cable television network rules and regulations, 1995, clause five, sub-sections 1(C) and 1(E), under which the operators must not telecast any programme that could incite communal hatred or come in the way of maintenance of the law and order.
