Following the attack on the Sunjuwan military station in Jammu, Defence Minister Nirmala Sitharaman said Pakistan "will pay for its misadventure"

The three heavily-armed Jaish-e-Mohammad (JeM) terrorists who carried out the audacious attack on Sunjuwan military camp in Jammu had infiltrated into Kashmir from Pakistan in June last year, army sources today said.

According to preliminary investigation of the Army, the three terrorists were hiding in various parts of Jammu and Kashmir for the past seven months and were looking at carrying out an attack.

Six army personnel and a civilian were killed in the attack on the Sunjuwan military station on February 10. Three JeM terrorists, who carried out the strike, were killed during the gun battle with the Army.

The JeM terrorists who carried out the attack had crossed over to India from Pakistan in June last year when infiltration had gone up, the sources said.

They said a detailed investigation is being carried into the Sunjuwan attack and the probe report will be examined by top echelon of the army. 

The sources said immediate steps are being taken to ensure that such attacks do not recur.
