Iraqi forces retook a town from the Islamic State jihadist group in Anbar province Thursday and evacuated 10,000 civilians as they advanced up the Euphrates valley, a security spokesman said. The sprawling province of Anbar -- which borders  Syria, Jordan and Saudi Arabia -- was at the heart of the "caliphate" that IS proclaimed in 2014. The jihadist group still holds most of the province but the noose is tightening around some of its key bastions.  / AFP PHOTO / MOADH AL-DULAIMIMOADH AL-DULAIMI/AFP/Getty Images
