In Afghanistan, a suicide bomber ambushed Afghan army cadets as they left their base in Kabul Saturday, killing 15 of them. The Taliban claimed responsibility for the bombing, as well as a rocket attack earlier in the day on a military base used by the U.S.-led coalition. On Friday, a suicide bomber attacked a Shia mosque in Kabul, killing 56 people and wounding 55 others during prayers. ISIS claimed responsibility for that attack. Separately, an attack on a Sunni mosque in central Afghanistan’s Ghor province killed 20 people. The attacks capped a week of violence that saw more than 250 people killed across Afghanistan.
