Pakistan's Foreign Minister Shah Mahmood Qureshi called his Iranian counterpart Mohammad Javad Zarif on Sunday to strongly condemn and offer condolences over the recent terrorist attack in south-eastern Iran.
During the phone conversation, Qureshi said a specialized Pakistani delegation will be sent to Iran later in the day to hold talks with Iranian officials.
"Pakistan is ready for any cooperation [with Iran] to probe into the regrettable incident, and for joint fight against terrorist groups," the Pakistani FM said.
Qureshi made the phone call after top Iranian officials, including the president, the IRGC chief, and foreign ministry officials strongly protested Islamabads failure to counter the terrorists operating inside its territory.
IRGC Chief-Commander Major General Mohammad Ali Jafari and President Hassan Rouhani both suggested that Iran may launch operations inside the Pakistani territory if Islamabad fails to identify and punish the Jaish al-Adl terrorists who killed 27 and wounded 13 Iranian border guards in their Wednesday attack.
Earlier in the day, Iran summoned the Pakistani ambassador to express its strong protest over the terror attack on a bus carrying IRGC border guards in Irans Sistan and Baluchestan province.
Foreign Ministry Spokesman Bahram Qassemi said the Islamic Republic conveyed its strong protest to the Pakistani diplomat during the meeting.
