In Iraq, security forces stormed Mosul’s airport and a nearby military base today as they sought to capture the city’s western half from ISIS. Mosul has been besieged since October, when U.S. special forces joined Iraq’s army, Shia militias and Kurdish fighters in a campaign to recapture the city from the self-proclaimed Islamic State. A military spokesperson admitted Wednesday U.S. troops have been wounded in the fighting, but would not say how many. Aid groups say they’ve prepared food and basic supplies for up to 400,000 civilians who are expected to flee the fighting.
