The US Treasury has asked Iraq to close all but two of its border crossings with Iran, Iraqi Foreign Minister Fuad Hussein said in an interview with Al Jazeera, as reported by Reuters. He said one of the two exceptions is in the Kurdistan region. Hussein said closing all the crossings would be difficult and would hurt Iraq's economy, since there are many official and unofficial crossings. He said the US is still demanding the closures as part of its policy of increasing economic pressure on Tehran.
