Lawmaker Mohammad Saeed Arbabi called on authorities to take strong action against terrorist groups in the southeastern province of Sistan and Baluchestan to ensure "lasting security" there.
"Unfortunately each time such (terrorist) incidents take place, authorities go so far as condemning them… nobody takes measures to track and detain the perpetrators to prevent the repetition of such incidents," ICANA quoted Arbabi as saying on Friday.
He added that Sistan and Baluchestan Province is developing rapidly but there are certain "elements and forces" who are seeking to hinder such development by causing insecurity through committing terrorist actions with the backing of foreign terrorist groups.
The lawmaker's comments came after unknown gunmen killed two people in separate attacks on Thursday night in the city of Sarbaz.
The attacks came only days after armed assailants killed three members of the Islamic Revolution Guards Corps (IRGC) in an ambush near the border city of Saravan in the same province near the Pakistani border.
Iran has a 300 kilometer-long stretch of joint border with Pakistan.
There has been a spate of terrorist attacks in recent years with gunmen crossing the porous border with Pakistan.
Iranian officials have frequently criticized Islamabad for not taking adequate action to prevent terrorist groups from using its soil as an operation base against Iran and prevent them from crossing the common border. Iran has even hinted it may be forced to enter into Pakistani territory "to confront terrorists."
