Iranian border forces have fired mortar shells which landed and exploded near a border area in bordering Chagai district in Pakistan's Balochistan province.

"Twelve to 15 mortar shells exploded between the border pillar No 12 and 15 between the night of Sunday and Monday," Balochistan Home Secretary Akbar Hussian Durrani told to Dawn.

However, no casualty was reported as the area is a desert along with Pak-Iran border.

Soon after the incident, Frontier Corps personnel rushed to the site.

"We have informed the Foreign Office about the incident," Durrani said.
