New Delhi, Mar. 3: Federal Bureau of Investigation (FBI) chief Robert Mueller arrived here on Tuesday to meet Home Minister P. Chidambaram, National Security Advisor M. K. Narayanan and other top functionaries of the government.

The FBI chief’s meeting with government officials over security issues, including counter terrorism, is expected to start this afternoon.

Official sources have confirmed that Muller will also meet Intelligence Bureau Chief Rajiv Mathur.

Mueller''s visit comes after India and the US shared details of intelligence and investigations in last year’s Mumbai terror attacks, a joint effort which forced Pakistan to admit that a part of the conspiracy was hatched on its soil.

The FBI’s collaboration in the investigations of the 26/11 Mumbai attacks were crucial, with detailed analysis of Voice over Internet Protocol (VoIP) and Global Positioning System of satellite phones used by terrorists. (ANI)
