According to the police, it was a pakistani terrorist that planned the whole thing. Makes sense... USA had been moving troops along the country preparing them for something, since Musharraf isn't being that cooperative. Now they have a reason to invade and everything.
k: India must be rejoicing now, since USA and India just recently signed a new defense pact. Amazingly, only took 10 days after the signing for USA & allies to find a reason to take Pakistan out...
