India's NDTV is now reporting new details, based on Indian intelligence sources, of the Mumbai attack, including the total number of attackers, their origins, etc. We'll have video shortly. Key details seemed to be that there were 40 attackers, half were there in place and in advance and half were brought in on speed boats from the sea. 29 were Pakistani, 11 were Bangladeshi.

I should emphasize here that while reports sourced to off-the-record statements from intelligence agencies should always be treated with caution, that is particularly the case here. The Indians come at these terrorist incidents with strong (and not at all unfounded) assumptions about Pakistani involvement. That may very well be the case. But we should wait for firmer evidence before taking these reports as the final word.
