Terrorist training camps were found in Hil Kaka region of Surankote district in Jammu during the army's recent six-week-long Operation Sarp Vinash.
Dummies and target shooting equipment were found in the camps, which had been there since early last year, official sources said.
According to a report with the home ministry, the camps were in Sukhiban, Mandi and Wansi forests in the Hil Kaka region. Boys from Kashmir and adjoining areas of Poonch and Rajouri were trained there.
The report said that in February-March this year, the army was told about the arrival of General Mossa, commander of the Jaish-e-Mohammed, at Hil Kaka to train 150 boys.
However, the operation was deferred due to heavy snowfall.
A large number of terrorists had also gathered at Poshana Dhoke, opposite the Suran River, the report said.
During the operation, the army authorities also found a full-fledged medical kit at Sinhali Dhoke and Lalpur Dhoke on Nainsukh Hil, a part of Hil Kaka.
Earlier, some of the Kashmiri boys rescued by the Special Group-III of the police had revealed that besides being imparted with arms training, they were made to carry heavy loads of Pakistani and Afghan terrorists and wash utensils.
No big bunkers were found during the operation except one in Banawali near Hil Kaka.
