Mortar shells were fired into Pakistani territory by Iran's border guards on Wednesday, media reported.
"Mortar shells fired by Iranian border guards landed in the district of Panjgoor," a provincial government official told Dawn News on the condition of anonymity.
The official added that two of the shells landed near Frontier Corps checkpost, and the third at Killi Karim Dad.
No property or human loss was reported in the shelling.
Security forces tightened security at the border after the incident.
Pakistan shares a 900-km long porous border with Iran and the two countries had in 2014 decided to boost intelligence coordination to wipe out terrorists from the border region.
