Unidentified gunmen killed nine Pakistani workers in a restive southeastern border area of Iran on Saturday, Pakistan’s ambassador and Iranian state media said, amid efforts by the two countries to mend ties after tit-for-tat attacks.

“Deeply shocked by horrifying killing of 9 Pakistanis in Saravan. Embassy will extend full support to bereaved families,” the Pakistani ambassador to Tehran, Muhammad Mudassir Tipu, said on the X platform. “We called upon Iran to extend full cooperation in the matter.”

Iranian state media said police were looking for the three gunmen who escaped after the shooting.
