Attack on Bodhgaya temple

Today at 5.05 am a multiple bomb blast took place at Bodhgaya around 130 km far from Patna, Bihar and Union Home Secretary Anil Goswami said the blasts were a "terror attack."  In the blast 2 people are injured and little damage has been done to the temple. The television is full of speculation and political party specially BJP is all over the Television with their voices against the Nitish government.
The speculation goes like this:

1. Intelligence was shared with the govt and police on the possible attack on Bodhgaya temple. On 25th June security drill was carried out. But amidst all these 8 serial blast took place.
2. 4 IM persons had done a reccee in September 2012 and this attack could be connected with IM. an analyst said that the module of the attack has IM signature.
3. There could be a connection with the Myanmar disturbance as many of the pilgrimages come from Myanmar.

Bihar is a fragile state with the history of communal wars and weakened Ranbir sena. Bihar has the local expertise on arms and explosion. Bihar is in news due to arrest of terrorists. Bihar has a porous border. If at all it is a terrorist attack then the local operators has a big hand to play.

The police official accepts the fact that there was intelligence alerts and on 25th June they had a security drill too. But amidst all the blast took place. The blast took place not only outside the temple but inside the temple premise too. How did the explosives got inside? One of the official in TV said that Police is responsible for the security out side the temple and the checking at the gate and inside security is managed by temple trust. So again the question arises where is the convergence and coordination between the two?

BJP is asking the govt what did they do with the intelligence alerts? But the irony is BJP was a part of Bihar govt till last month. Politicising this blast would not help the state.
What we need is a robust Risk Management. There should be a convergence of departments at all levels.
