Pakistani troops have seized a camp used by the extremist group blamed in last month's Mumbai attacks, the Associated Press reported, citing two militants

The militants say troops arrested more than 12 people during the raid Sunday close to the town of Muzaffarabad in the Pakistani part of the disputed Kashmir region. They say there was a brief exchange of fire during the operation.

Pakistan authorities were not available for comment Monday.

The militants say the camp was used until 2004 by the banned Lashkar-e-Taiba to train recruits to fight Indian rule in its section of the Kashmir.

More recently, it was used by Lashkar's parent organization, Jamaat-ud-Dawa, for education and charity work, they say.

The attacks on India's financial capital killed 171 people and wounded 239. Among the dead were two Canadians.

The sole surviving gunman in the attacks, Ajmal Amir Kasab, 21, has told interrogators he was sent by the Lashkar group, which has fought against India's control over part of Kashmir.
