BAGHDAD (AP) — Iraqi forces have made significant progress as they close in on the Islamic State-held town of Tal Afar, west of Mosul, the U.S.-led coalition said Monday. U.S. Army Col. Ryan Dillon, a coalition spokesman, told The Associated Press that Iraqi forces have retaken some 250 square kilometers (95 square miles) from the extremist group, though they have not yet pushed into the town itself. "As we get into the urban areas — as we saw in Mosul and Raqqa — that's where we'll see the pace slow down, that's where (IS) have placed their defenses," he said. U.S.-backed Iraqi forces drove IS from Mosul last month after a grueling, nine-month campaign to retake the country's second largest city.
