Meanwhile, the army, Border Security Force (BSF) and Punjab police conducted a five-hour-long joint flag march in border villages today to instill confidence among people, SSP Rakesh Kaushal said.
These measures were being taken to dispel any fears locals might have, he said.
The SSP said vigil at the border, especially in 20 villages located near the zero line, has been increased.
