Both are allegedly affiliated with Lashkar-e-Taiba, a group previously known for attacks in the disputed territory of Kashmir, The New York Times reported. The group has denied carrying out the Mumbai assault.

Mohammed Ajmal Kasab, a 21-year-old Pakistani who is the only known survivor among the terrorists, allegedly told police that Zaki-ur-Rehman Lakhvi was involved with coordinating the group's actions and indoctrinating its members. Indian and U.S. intelligence agencies say the assault was plotted by Yusuf Muzammil and that the 10 men who went to Mumbai talked to him by phone during their sea voyage from Karachi.

Another man, Faheem Ahmed Ansari, was allegedly involved in casing Mumbai to help plan the attack. Ansari was arrested in February in Uttar Pradesh, where he was allegedly involved in a New Year's Eve attack on a police camp.
