Iraqi military officials say Sunni fighters have captured two border crossings, one with Jordan and another with Syria, as they press on with their offensive in one of Iraq's most restive regions.
The officials said the fighters captured the Turaibil crossing with Jordan and the al-Walid crossing with Syria on Sunday after government forces there pulled out.
The officials spoke on condition of anonymity to the Associated Press because they were not authorised to speak to the media.
The fighters seized another town in Iraq's western Anbar province, the fourth to fall in two days, officials also said.
Chief military spokesman, Qassim al-Moussawi, acknowledged the fall of the Anbar towns, saying government forces had made a tactical retreat and planned to retake them. He provided no further details.
