Role of Media is being terrorist aids

During the three day operation from 26 - 29 Nov, we saw the electronic and visual media providing all the latest and upto date information to its audiences. We saw them discussing the strategies being adopted by the authorities to contain the attack, the actions taken by the commandos, the trauma of the hostages while they were actually trapped, etc. How do we justify this? Was media involved and responsible for providing all the information that terrorists needed to be able to stretch the operation for 3 days and kill more than 200 people? Is it justified for the media to give such a wide coverage to a classified event?
