Deputy High Commissioner J P Singh was called to the Foreign Office in Islamabad and given a note verbale by the Pakistani Foreign Office which lodged the protest over the incident, sources said.
In the morning, Pakistan Rangers targeted a BSF patrol party by resorting to firing along the International Border in Samba district. In the heavy firing, one BSF jawan was killed.
In BSF's strong retaliating, some Pakistani rangers were killed.
The retaliation which forced the rangers to wave white flags came on a day when the Government asked the Border Security Force to provide a "suitable and appropriate reply" for any unprovoked firing from across the Indo-Pak border.
Wednesday's firing by Pakistan in which one jawan was also injured was the second ceasefire violation along the IB in the past 24 hours.
