A peer-reviewed literature search included three databases (PubMed, ProQuest and Embase), and a grey literature search included reports from groups involved in the Syrian health response or human rights monitoring.Findings From 2016 to 2017, there were 204 individual attacks involving 243 ambulances. Half (49%) were either heavily damaged or put out of service. The main perpetrators were the Syrian regime (60%) and the Russian armed forces (29%). Half (52%) of ambulances were directly targeted. The peer-reviewed literature search yielded 18 articles, from which the following themes were drawn: targeting of ambulances, ‘double-tap’ attacks, delays to care, obstruction and other forms of violence, and long-term consequences.Interpretation Ambulances have been intentionally and repeatedly targeted throughout the Syrian conflict as part of a war strategy. Real challenges in monitoring and systematically tracking attacks on ambulances exist, but as a result, they are understudied and likely under-reported.
