An Army captain was killed and four terrorists were believed to be gunned down in an ongoing operation in the higher reaches of Jammu region's Doda district on Wednesday, officials said.

A civilian was also injured in the encounter that broke out a day ahead of Independence Day and is the latest in a series of incidents in the Jammu region that has witnessed a spike in violence.  Bullets rang out Wednesday morning in a thickly forested area during a cordon and search operation (CASO) launched by a joint team to track down a group of foreign terrorists hiding in the Shivgarh-Assar belt, officials said.    Captain Deepak Singh was critically injured during the operations and shifted to a military hospital where he breathed his last, they said.
