The set of 30 questions — which were handed over to Indian High Commissioner Satyabrata Paul by Pakistan’s Foreign Secretary Salman Bashir — include requests for the DNA reports and fingerprints of all the 10 terrorists, data from the cellphones, satellite phones and GPS devices used by the attackers, as well as Voice Over Internet Protocol (VoIP) data, voice recordings and radio intercepts. Islamabad has also asked for details of the weapons and ammunition used by the terrorists along with ballistics and explosives reports.

A cluster of questions also pertain to the names and contact details of the lead investigating agency in India. While the Mumbai Police are handling the case in India, it is being handled by the Federal Investigation Agency in Pakistan.

Sources said that discussions with the Mumbai Police have already taken place for preparing responses to Pakistan’s questions. This followed a February 12 meeting that included External Affairs Minister Pranab Mukherjee, Home Minister P Chidambaram and Defence Minister A K Antony. The Home Ministry has also initiated discussions with the Intelligence Bureau (IB) and the Research and Analysis Wing (RAW).

However, India has not yet spelled out any time-frame for responding. The Ministry of External Affairs had, on February 12, said New Delhi will share “whatever it can”. On Tuesday, Pranab Mukherjee had told Parliament that India will respond as and when it is ready.
