Sources on civilian casualties

The main source on civilian fatalities in Syria used in this report is the Syrian Network of Human Rights (SNHR). The Syrian Network for Human Rights (SNHR) is a non-profit human rights organisation founded in 2011 which works on documenting human rights violations in Syria. SNHR relies on a network of volunteers in each governorate to compile lists of civilian fatalities and verify victims’ identities by photo or video and by speaking with family members, witnesses, and hospitals. SNHR reports fatalities by gender, age, perpetrator, governorate, and other classifications. It only records civilian fatalities.14 SNHR provided EUAA with a dataset covering the reference period from October 2025 to May 2026. SNHR data used for the period from 9 December 2024 to the end of September 2025 was based on the following two EUAA publications: Syria – Country Focus from July 2025 and Syria – Major human rights, security, and socio-economic developments [Q33-2025] from October 2025. Please note that SNHR may have revised the numbers retroactively.

Where available, information from other sources documenting civilian casualties in the Syrian conflict (Office of the High Commissioner on Human Rights, the Syrian Human Rights Committee, Action on Armed Violence, the Syrian Observatory for Human Rights) has been included.
