India says Pakistani government involved in Mumbai.

I don't know enough about Indian politics to put this in context, but this represents a substantial raising of language, especially coming from the Indian PM.

November's attack on Mumbai must have had support from some official agencies in Pakistan, Indian Prime Minister Manmohan Singh has said.....

Mr Singh again criticised Pakistan's policies on tackling terrorism, saying it had "given sanctuary to terrorists and other forces who are antagonistic to India".

In the NYTimes, the allegation seems to be in terms of "elements (ISI/military) must have been involved" rather than hard proof. "Retired officers" seems to be the closest they come to hard links.

In a presentation to a number of foreign diplomats earlier in the day, Indian officials detailed the involvement of retired Pakistani military officials in training the gunmen who carried out the Mumbai attacks, according to two diplomats present.

Everybody knows the links are true, but no hard proof yet.
