Government forces breached the city limits of Tal Afar in northwestern Iraq on Tuesday on the third day of a U.S.-backed offensive to seize it back from Islamic State militants.
Tal Afar, a longtime Islamic State stronghold, is the latest objective in the war following the recapture of Mosul after a nine-month campaign that left much of that city in ruins.
U.S. Defense Secretary Jim Mattis, speaking just before arriving in Iraq on Tuesday, said the fight against IS was far from over despite recent successes by the Western-backed government. The Sunni Muslim jihadis remain in control of territory in western Iraq and eastern Syria.
