Russia claimed Friday that Abu Bakr al-Baghdadi, the leader of ISIS, was killed in a May airstrike just outside Raqqa, the group's capital city. In a later statement, Foreign Minister Sergey Lavrov said they didn't have "100% confirmation."
- Details, per AP: "The Defense Ministry said the air raid on May 28 that targeted an IS meeting held on the southern outskirts of Raqqa in Syria also killed about 30 mid-level militant leaders and about 300 other fighters."
- The case for caution: "There had been previous reports of al-Baghdadi being killed but they did not turn out to be true."
- The U.S. isn't commenting: "The spokesman for the U.S.-led anti-IS coalition said in a statement Friday he could not confirm the Russian claim."
