Indian Army had also retaliated by firing. However, no loss from other side is known.
The injured soldiers were rushed to the nearest hospital.
According to the BSF officials, the three injured soldiers are out of danger.
The jawans from Border Security Force, who were in their positions at the Dakute Post near Amritsar got injured after Pakistan Rangers opened fire on Friday night.
Pakistan has been continuing its attack in the area for the past few months to provoke the Indian Army.
According to reports, the attack against BSF troopers is noticed as the third incident which happened in last one month at India-Pakistan international border in Punjab.
It is sure that the provocations from Pakistan will be considered seriously by the Defence ministry and hold talks with other side regarding the firing and attacks.
The Pakistani smugglers have concentrated their activity in the area and smuggling through Punjab border had also increased.
The role of infiltrators in the attack is also greater, as they are thriving for an entrance into the Indian Territory.
Few days back, AK-47 rifle was found near the international border area in Punjab and with passing days the incidents of smuggling are also increasing.
Pakistan's fresh round of border firing across the international border in the Punjab region has surely raised many questions.
