Iraq’s army on Thursday declared an end to the so-called Islamic caliphate, as the U.S.-backed coalition captured the ruins of the Grand al-Nuri Mosque in Mosul from ISIS. The mosque was the site where ISIS leader Abu Bakr al-Baghdadi declared the caliphate in 2014. Its capture came as Iranian media reported Baghdadi is “definitely dead.” That follows Russian reports last month that Baghdadi died in a Russian airstrike in Syria. Meanwhile, heavy fighting continues in parts of Mosul, where tens of thousands remain trapped in the Old City with little access to food, water and medicine. The journalistic monitoring group Airwars reports at least 80 civilians were killed Thursday after shelling and airstrikes hit their houses around the Grand al-Nuri Mosque. That follows reports that a family of five was killed and a 4-year-old boy was severely injured in an airstrike by the U.S.-led coalition on Tuesday.
