On 1 May 2016, twin suicide car bombs exploded in the city of Samawa, located in Iraq's deep Shiite south, an area where such attacks were considered rare at the time. The first blast occurred near a local government building, with a second explosion following roughly 65 yards away at a bus station. Police sources cited in the reporting indicated the death toll and number of wounded were expected to continue rising in the immediate aftermath.
The attacks killed at least 33 people and wounded 75 others. The Islamic State claimed responsibility for the bombings. The individuals identified as the bombers were named as Abu Dayyar al-Qurashi and Abu Zubayr al-Zaidi.
The bombing occurred amid a period of continued violence in Iraq, with the Samawa attack singled out as notable in part because of its location — a predominantly Shiite region in southern Iraq that had experienced comparatively fewer such incidents than other parts of the country.
