 Pakistan has hit Iran with what it described as highly coordinated military strikes, a little more than 24 hours after Iranian air strikes in Balochistan. Islamabad said its forces launched a series of highly coordinated and specifically targeted precision military strikes in Iran's southeastern Sistan and Baluchistan province as part of an operation called, Mard Bar-Sarmakar, a phrase which loosely translates to death to the guerrilla fighters.A number of militants were killed during the operation, Pakistan's foreign ministry added. Tehran demanded an immediate explanation from Pakistan over the strikes, Iranian state-aligned Tasneem News Agency reported, citing an official, over the last several years, in our engagements with Iran, Pakistan has consistently shared its serious concerns about the safe havens and sanctuaries enjoyed by Pakistani origin terrorists calling themselves Sarmakars on the ungoverned spaces inside Iran. Pakistan also shared multiple dossiers with concrete evidence of the presence and activities of these terrorists, the Pakistan's foreign ministry said in a statement, however, because of lack of action on our serious concerns, these so-called Sarmakars continue to spill the blood of innocent Pakistanis with impunity. This morning's action was taken in light of credible intelligence of impending large-scale terrorist activities by these Sarmakars. This action is a manifestation of Pakistan's unflinching resolve to protect and defend its national security against all threats. Iranian state media said that a attack killed at least seven people.
