Iran opened a border crossing with the Iraq's Kurdistan Regional Government (KRG) on Wednesday which was closed after an illegal referendum on independence in the area, Iranian state media reported.

"After the referendum and changes within the Kurdistan region our borders with the Kurdistan region of Iraq were closed... today the Bashmagh border is open," Jahangir Bakhshi, the head of customs for the border crossing, said, according to the Islamic Republic of Iran Broadcasting (IRIB) news agency.

Iran's consulate in Irbil confirmed the reopening, saying it was done at the request from residents of Sulaimaniyah province.

"No decision has been made so far on reopening other border gates of Iran with northern Iraq," the consulate added.

Iran has three main crossings with the Kurdish region; Haji Omaran (in Irbil province), Parwezkhan, and Bashmagh.
