Islamabad, Pakistan (CNN) Pakistan said it is not bowing to Indian or international pressure as it cracks down on militant groups in the wake of the crisis over Kashmir.

On Tuesday, authorities said they detained 44 members of banned organizations, including the son and brother of Masood Azhar, the leader of militant group Jaish-e-Mohammed (JeM).

JeM claimed responsibility for a suicide bombing in Pulwama in Indian-controlled Kashmir on February 14, which resulted in the deaths of 40 Indian troops and precipitated the current escalation in tensions between the two nuclear-armed powers.

Speaking to CNN, Pakistan's military spokesperson, Maj. Gen. Asif Ghafoor, said that any clamp-down on militants was part of an ongoing domestic policy.

"We are not doing anything under anyone's pressure," Ghafoor said Tuesday, adding that Pakistan would root out "anybody who operates from Pakistan ... we feel that it is not in the interest of Pakistan."
