crisis in yemen
At least 50 people were killed and dozens more wounded by a suicide bomber in Yemen Saturday morning. The attack took place on a Yemeni army base in Aden where troops had lined up to collect their paychecks, and the Islamic State claimed responsibility for the bombing several hours after the incident in a statement online.
Other extremist groups including al Qaeda are also active in the region and have taken responsibility for similar strikes in the past. For more on Yemen's civil war, including Saudi Arabian and American involvement, see this analysis from The Week's Michael Brendan Dougherty.
