Sunni fighters led by the Islamic State in Iraq and the Levant (ISIL) have expanded their offensive in Iraq, capturing more territory from the government.
ISIL active in Syria and Iraq has taken the towns of Qaim, Rawah and Anah in Anbar province.
Qaim, located on the border with Syria, hosts a key crossing between the two countries, Al Jazeera reported.
Fighters also claimed to be in full control of the northern city of Baiji, which hosts Iraq's biggest oil refinery, though the military denies the rebels control the refinery itself.
The Associated Press news agency, citing Iraqi miltary official, reported that Sunni fighters captured two border crossings, the Turaibil crossing with Jordan and the al-Walid crossing with Syria, on Sunday.
Al Jazeera's reporter in Baghdad witnessed significant ISIL movement in Anbar, which is leading the province increasingly and coming under the control of fighters.
"After taking over Qaim, Rawah and Anah, armed groups are now advancing to the next town, Haditha in the west of Ramadi city, and are negotiating with tribal leaders to enter there peacefully," he said.
