India Has Proof Pakistan's ISI Authorized Mumbai Attacks?

According to NDTV, it is so:

More than a week after the Mumbai attack, sources have told NDTV that India has proof that the ISI mastermined the Mumbai attack. Sources in fact say that they are 100% certain that the attack was authorised by Pakistan's intelligence agency. They say the attack was very well organised, with sophisticated equipment and logistics.

Sources say India has specific evidence on the ISI's role -- the names of the ISI trainers and the names of the places where the terrorists were trained. In fact sources say it doesn't appear that the terrorists simply took a chance and hijacked an Indian boat to come to Mumbai. There was definitely more planning than that. 

Sources say that given the close links between the ISI and the army, they find it hard to imagine that the army wasn't aware of this plot. But here's a crucial point. They say they don't believe President Asif Ali Zardari's civilian government is involved. In fact they described Zardari as irrelevant -- even as a power tussle takes place between him and the army-ISI combine.

Sources say the Mumbai attack could have been one way of the army and the ISI reasseerting that they call the shots and that there could be a strategy by the army to take over power if tensions with India significantly rise.

The other important information is that Admiral Mike Mullen, the head of the US joint chiefs of staff, has told Islamabad they have to arrest Lashkar-e-Taiba (LeT) chief Hafeez Sayeed. And that there is no point denying it. The Americans have evidence. Sources in fact say America has a lot of evidence on the attacks and has shared that information with India.
