Lahore: Pakistani authorities have shut down several religious schools run by the Jaish-e-Mohammad militant group accused of masterminding an attack this month on an air base in India, the provincial law minister said on Friday.

The crackdown in Punjab province, Prime Minister Nawaz Sharif`s power base and the headquarters of Jaish-e-Mohammad, follows the arrest this week of several members of the militant group, including its leader, Maulana Masood Azhar, an Islamist hardliner and long-time foe of India.

Pakistan has said it is clamping down on Azhar`s group, which India has long accused Pakistani authorities of tolerating, while it investigates Indian assertions that the January 2 attack on the Pathankot air base was the work of the Pakistan-based militants.

“Officials of the Counter-Terrorism Department raided the Jamiatul Nur seminary in the Daska area on Thursday and arrested more than a dozen people,” Rana Sanaullah, the law minister of the Punjab province where Jaish-e-Mohammad is headquartered, told Reuters.

“The seminary has been sealed off and documents and literature have been confiscated from the premises.”
