The attack occurred outside a building in Palmyra where officials from Syria’s Interior Ministry had travelled from Damascus to meet their local counterparts. According to a US official, American soldiers and their interpreter were outside the building when a lone gunman opened fire from a nearby structure with what appeared to be a machine gun. Three additional American service members were wounded, as were two members of the Syrian security forces.

The American soldiers who were killed were part of an Iowa National Guard contingent assigned to the Syria mission, according to Iowa Governor Kim Reynolds. US Central Command said the wounded Americans were evacuated by helicopter to the al Tanf garrison near the Jordanian and Iraqi borders, where they received medical treatment.
