Gunmen have killed nine Pakistanis in a restive southeastern border area of Iran, Pakistan has said, amid efforts by the two countries to mend ties after recent 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 Tipi, said on the social media platform X on Saturday. “We called upon Iran to extend full cooperation in the matter.”
