Iranian border guards reportedly fired four mortar shells into the Pakistani territory in Panjgur district on Saturday.
Levies sources said the mortar shells landed almost 120 metres inside Pakistani territory, however, no loss of life or property was reported.
Frontier Corps, Levies and other law enforcement personnel reached the spot and security was tightened following the border violation by Iranian border forces.
Panjgur Deputy Commissioner Mujeeb Qambrani lodged protest with the Iranian border guards with regard to violation of the territory.
“The deputy commissioner dispatched a letter to his Iranian counterpart,” a senior administration officer in Mekran Division said.
Iranian forces have been violating Pakistani territory for the last few years. Civilians were also killed during Iranian attack in Mashkail and other areas close to the Iranian border.
Pakistan has accused Iranian forces of violating its territorial integrity and has lodged protest with Iran in this regard several times in the last few years.
Pakistan shares a 900 kilometres long porous border with Iran and the two countries had last year decided to boost intelligence coordination to wipe out terrorists from the border region.
