"Pakistan Rangers opened fire on a Border Security Force (BSF) post in a R.S. Pura area of Hiranagar sector of the international border in Samba around 9.30 p.m.," said a paramilitary force officer.
BSF troopers retaliated, and the firing was still continuing as of 10.30 p.m., he said.
In the earlier incident, Pakistan Rangers opened fire at Pargwal post of the BSF in Akhnoor sector of the international border at 12.30 p.m., injuring a woman and four children.

The Pakistan Army and paramilitary forces continue to violate the November 2003 ceasefire and such transgressions have increased in the recent past.
