A mastermind of the killing spree in Mumbai, India, was among about a dozen militants arrested at an alleged terrorist training camp in Kashmir, Pakistani officials said Monday.
The camp, in the Pakistani-administered portion of Kashmir, is run by Lashkar-e-Taiba, a militant group blamed for last month's attacks in Mumbai that killed at least 171 people.
A man alleged to be one of the masterminds of the attacks in India, Zaki-ur-Rehman Lakhvi, is among those detained, NPR has confirmed.
Indian officials have said the sole Mumbai attacker captured alive has told them that Lakhvi recruited him for the mission and that Lakhvi and another militant, Yusuf Muzammil, formulated the plan for the attacks.
U.S. and Indian suspicions that Pakistan-based militants carried out and plotted the attacks have sharply raised tensions between South Asia's only nuclear-armed nations.
Lashkar-e-Taiba is one of several groups that has been fighting for two decades to end Indian control of Kashmir.
