Iran called for Iraqi officials to heed to principles of mutual relations and security when talking about PJAK terrorist group, ISNA reported.
"We are continuing negotiations with Iraqi officials on PJAK group and any comment on the issue should consider principles of bilateral ties and establishment of security and development," Iranian Foreign Ministry Spokesman Ramin Mehmanparast told reporters in his weekly press conference on Tuesday.
His remarks came following remarks of Iraqi Vice President Tareq al-Hashemi and Foreign Minister Hoshyar Zebari who criticized Iran's treatment with PJAK terrorist group.
"Backing terrorism is not in favor of any country and uprooting terrorism needs comprehensive cooperation," Mehmanparast added.
Meanwhile regarding oil payment dispute between Iran and India, he said, "the way of Indian payment for Iran's oil will be specified in future."
"Technical experts of the two countries are continuing talks and that a large part of the issue has been settled," he added.
