Who was behind the attack? Is this their master plan?

The two persons in the above picture are not the army men. Its beleived to be two of the terrorists who attacked Mumbai.

The terrorists had no care of their lives. If they had minded sure they would have not had such an attack. The attack was very well done by them. They have chosen the places well so that they have some time before the Indian army get into act. Actually they would have planned this at least before 3 or 4 months. The terrorists are well aware of the places and the infra structure of the hotels they attacked. It is not possible for them to have the information without the help of some local. Might be its not their major plan. Also there is no confirmation of how many terrorists entered India and by which means. It would be rather bad to know if lots of them have entered. May be this attack is to divert the whole nation towards the attack and they might have a simultaneous operation somewhere. Its our security departments duty to make sure about these details from the terrorists they have arrested.
