Indian officials say the sole Mumbai attacker captured alive has told them that Lakhvi recruited him for the mission and that Lakhvi and another militant, Yusuf Muzammil, planned the operation, which left 171 people dead in India's commercial capital.
The capture of Lakhvi was likely to please India as well as U.S. officials, who allege he also directed Laskhar-e-Taiba operations in Chechnya, Bosnia and Southeast Asia, training members to carry out suicide bombings and attack populated areas. In 2004, he allegedly sent operatives and funds to attack U.S. forces in Iraq.
It was not immediately clear what Pakistan intended to do with Lakhvi.
