Amnesty International, an international rights group, urged the U.S.-led military coalition battling the Islamic State group to investigate airstrikes that killed civilians in the campaign to liberate the Syrian city of Raqqa from the extremists. Amnesty said Tuesday, Aug. 7, 2018, that the U.S.-coalition’s admission last month that it killed 78 more civilians than previously reported in the 2017 assault on Raqqa was just the “tip of the iceberg.” (AP Photo/Hussein Malla, File)
