IMO that is a very lame reason because of the following reasons.
1. Many people in D.I.Khan are using long range cordless phones like Senao, according to the above quoted reason then ptcl should also b banned.

2. If we go by this reason then Karachi is the first city where we need to shut down all the cellular networks.
According to my info mobile networks were jammed in DIKHAN, Bannu and other areas neighbouring the tribal belt, with the start of Operation Rah-e-Nijat in South Waziristan Agency and its long operation has been over but the cell networks are still jammed.IMHO Mobile is not the only tool to facilitate sect killings but what to say 
PS Feeling sorry for the young love birds of DIK
