A BSF jawan's throat was slit and his body bore multiple bullet injuries after the missing trooper was found killed by Pakistani troops in the Jammu region, in a first of its kind barbaric act against Indian forces along the International Border, officials said on Wednesday.

The officials said a "high alert" has been issued to all formations along the 192-km long International Border (IB) and the 740-km LoC, which is manned by the Army. The brutal incident in Ramgarh sector on Tuesday was reminiscent of similar attacks in the past against Indian security forces along the LoC.
