The US Treasury has formally asked Iraq to close all but two of its border crossings with Iran as Washington increases economic pressure on Tehran, Iraqi Foreign Minister Fuad Hussein said in an Al Jazeera interview aired Sunday. Washington proposed keeping one crossing in Iraq’s Kurdish Region and another elsewhere, although the locations and the scope of any restrictions remain undecided. Hussein said it was unclear whether the measures would cover visitors, commercial traffic or all cross-border movement, warning that closures would halt trade and movement and damage Iraq’s economy. Iraq’s official and unofficial crossings with Iran extend from the Kurdish Region to Basra. The request comes as the US Central Command announced a task force to disrupt Iran’s use of land routes for advanced weapons and other materials. Hussein also said Iraq lost about $60 billion after it could not export oil through the Strait of Hormuz for roughly four months at the start of the war, compared with exports of about 3.3 million to 3.4 million barrels a day before the disruption. He warned that regional military operations could resume, said Baghdad opposed attacks on neighboring countries from Iraqi territory, and described investigations into an attack on Saudi Arabia allegedly launched from Iraq near the Iranian border. Separately, Iraq’s prime minister has reached understandings with four armed groups on placing their weapons under state control, while talks continue with two others. Iraq had also closed the busy Sheeb crossing the previous month to review security and install detection equipment aimed at stopping smuggling.
