An Iranian lawmaker has asked Pakistan to put in place rigorous border controls.
The call from Ahmad Bakhshayesh came weeks after more than a dozen Iranian border guards were killed in a border region.
According to the Nation, Bakhshayesh said failing this Iran will pursue and target terrorists inside Pakistani territory.
If the Pakistan government does not pay attention to Iran's demands on strict border control, it should expect to see Iranian drones in its skies in pursuit of terrorists, Bakhshayesh warned.
Armed bandits had killed 14 Iranian border guards in an ambush near the border with Pakistan and fled into the country after the deadly attack.
According to the report, Bakhshayesh, who is a member of the Parliament's National Security and Foreign Policy Commission, added that the country's armed forces should be more vigilant in the eastern parts of the country as terrorists can sneak into Pakistan after carrying out an attack.
A group of armed men had carried out an ambush attack on October 25 on a border post in Gazbostan, near Iran's southeastern city of Saravan, on the border with Pakistan, killing 14 border guards and injuring six others, the report added.
