Highly placed sources shared the contents of a ‘Secret’ note that contains 35 mobile numbers. Of the 35 SIM cards, 32 had been purchased from Kolkata and three from Delhi, by “overground” workers of the Lashkar-e-Toiba, and sent to Azad Kashmir by mid- November. The precise contents of the ‘Secret’ note could not have been more direct: “The numbers given below have been acquired from Kolkata by overground workers (OGWs) and have been sent through Pakistan trained militants based in Kashmir to ***. These numbers are likely to emerge in other parts of the country. These numbers need to be monitored…” The note contains more: “These numbers need to be monitored and the information taken from these numbers regarding the contents of the conversation, current locations of the call detail records are required for further developing the information. The monitoring is possible at Kolkata.”
Highly placed sources reveal that this crucial and stunning piece of information was received by the Intelligence Bureau (IB) on 21 November, at least five full days before Ajmal Amir Kasav, the lone surviving terrorist and his nine accomplices got off the inflatable dinghy at Mumbai’s Badhwar Park on the evening of 26/11. The Prime Minister and Home Minister are aware that for all the five crucial days that the numbers were available, they were not being monitored. The lapse is all the more critical because at least three of the 32 numbers contained in the Secret note, were the exact same cell numbers that the Mumbai terrorists used to keep in touch with their handlers in Pakistan. It is well possible that the terrorists only activated their mobile numbers after reaching Mumbai but that does not excuse the fact that the numbers were not put under surveillance despite the knowledge that they had been sent to trained militants in ***.
Further the report says
On 18 September, for example, the Research and Analysis Wing had intercepted a satellite phone conversation which clearly indicated that a hotel at the Gateway of India in Mumbai would be targeted. Crucially, the intercept also revealed that the sea route would be used to launch this operation. Again, on 24 September, RAW recorded another conversation. This time, the hotels were mentioned by name and they included the Taj, the Sea Rock Hotel and the Marriott hotel. If these inputs were being analysed, it would have become clearer that hotels in Mumbai would be attacked and that the sea route would be used.
THIS IS not all. Again on 19 November, RAW picked up another piece of conversation in which a voice
said, “We will reach Bombay between nine and 11.” RAW tracked the coordinates of the call and frighteningly discovered that it came from the sea near Mumbai. RAW passed on this vital piece of information to the IB who in turn sent it to the Navy but the terrorists, who were first aboard the hijacked trawler MV Kuber and subsequently on the inflatable dinghy, still managed to sail into Badhwar Park, ironically, almost at the promised time: between nine and 11.
