In less than 24 hours after Pakistani Rangers had sniped and killed a BSF trooper in an unprovoked firing across the international border, the Border Security Force (BSF) taught Pakistan a lesson in a heavy round of retaliation.

BSF achieved success by destroying two mortar positions in Sukhmal area of Pakistan Rangers. India Today has found out that the Pakistan side suffered a heavy casualty with a minimum of 10 soldiers being killed.

Confirming heavy damage, IG Ram Avatar said, "we have destroyed at least four borders outposts. We have inflicted a heavy damage on them for unprovoked Pakistan action at the border."

Ram, however, declined to give an official figure on the number of Pakistani Rangers killed. No official complaint has come forward from Pakistan's side.

The incident occurred around 4 p.m. on Wednesday when BSF began inflicting damage on Pakistan's side with a continuous exchange of fire between the two sides continuing up to midnight.

Martyred trooper Head Constable Radha Pad Hazra had put in 27 years of service. A resident of West Bengal's Murshidabad, the jawan breathed his last on his birthday.

Constable Hazra is survived by his 21 year old daughter and his 18 year old son.

Despite best efforts, Hazra was evacuated immediately to a nearby medical facility but succumbed to his injuries later.

The unprovoked fire from Pakistan started first from small arms which was later coupled with mortar shelling.

BSF troopers consolidated their positions, located and marked Pakistan firing spots and started with precision targeted firing.

Two Pakistan mortar positions were targeted and destroyed by BSF troopers on Wednesday night. The coordinated precision fire of BSF troopers silenced Pakistan guns.

Since the beginning of New Year, the BSF has maintained extra vigil on Jammu international border to foil infiltration attempts by miscreants which are aided by Pakistani forces from across the border.

"Firing across international border is most of the time a diversionary tactic to facilitate intrusion," said BSF personnel.

During winters, once snow covers the passes in Kashmir valley, Pakistan shifts attention to the LoC and international border in Jammu sector indulging in unprovoked firing.

Keeping in mind Pakistan's tactics as terrorists attacked Pathankot airbase in January 2015 entering from BSF manned border area in Punjab, the force has not let it's guards down.

On Thursday, despite dense fog in RS Pura area troopers detected an intrusion attempt around 5:45am.The intruder was later neutralized as per BSF
