The chief of global police agency Interpol on Tuesday met with Pakistan's interior ministry chief after pledging to help India investigate last month's attacks in Mumbai.
Ronald Noble met with Rehman Malik, who has been leading Pakistan's counter terrorism efforts, to discuss both the Mumbai investigation and the devastating September suicide attack on the Marriott Hotel in Islamabad.
Noble was to hold a press conference after his talks with Malik, interior ministry spokesman Shahidullah Baig told AFP.
Interpol said in a statement that Noble would "seek Pakistan's agreement to work through Interpol to help identify terrorists worldwide, including those behind the deadly 26-29 November terrorist bombings in Mumbai."
Noble, who met with the head of Pakistan's Federal Investigative Agency on Monday, said that only the sharing of critical police information on terrorism" could help prevent attacks like those in Mumbai and Islamabad.
New Delhi has blamed last month's attacks, which left 172 people dead, on the banned Pakistan-based militant group Lashkar-e-Taiba (LeT).
India says the gunmen were trained and equipped by LeT and travelled to Mumbai on a hijacked trawler from the Pakistani city of Karachi. The group has denied any involvement.
Under pressure from India and the United States, Pakistan has cracked down on the group and an Islamic charity regarded as a front organisation, but New Delhi says it has not done enough.
Noble met with Indian Home Minister P. Chidambaram at the weekend and promised to help New Delhi gather information about the 10 attackers, nine of whom were killed.
The lone surviving gunman, Mohammed Ajmal Amir Iman, is in Indian custody.
He has reportedly written a letter which says he and the other attackers were Pakistani nationals, requesting assistance from Pakistani diplomats in the Indian capital. Islamabad says it is examining the letter.
