Jammu, Sep 18 - Two Border Security Force (BSF) men were injured in firing by Pakistani troops that continued Friday, military sources said.

The first burst of firing took place Thursday evening and it was directed at the Nikowal border post, about 30 km west of Jammu.

It wasn't clear to Indian officials if the firing came from Pakistani troops or the army which trains Muslim militants it sends to other countries. A military official told IANS on the condition of anonymity, if firing did come from Pakistan Rangers, then it could be deemed as a violation of the India-Pakistan row.
