PHR's comprehensive map tracks 150 attacks on 124 medical facilities in Syria, resulting in the deaths of 468 medical personnel since March 2011. The majority of attacks (90%) were committed by government forces, while anti-government armed groups were responsible for most recent attacks (9 out of 10). The governorates of Rif Dimashq and Aleppo reported the highest numbers of facility attacks, with Rif Dimashq and Homs governorates reporting the highest numbers of medical personnel killed. PHR used a variety of open sources, including UN reports, news articles, social media posts, and field research, to collect data for the map. The map was created using CartoDB's platform, which allows for real-time updates and customization. PHR used different visualizations, such as cluster maps and choropleth maps, to represent attacks on medical personnel and facilities, respectively.
