According to various sources, including the United Nations, up to 11,545–16,500 people have been killed, of which about half were civilians, but also including 4,000–6,300 armed combatants from both sides and up to 1,400 opposition protesters.[33][47][48][49][28] Many more have been injured, and tens of thousands of protesters have been imprisoned. According to the Syrian government, 7,480–9,785 people, including 2,845–3,375 members of the security forces, 1,155–3,000 insurgents and up to 3,500 civilians, have been killed in fighting with what they characterize as "armed terrorist groups".[38] To escape the violence, tens of thousands of Syrian refugees have fled the country to the neighboring countries of Jordan,[50] Lebanon, and Turkey.[51] The total official UN numbers of Syrian refugees reached 42,000 at the time,[52] while unofficial number stood at as many as 130,000.
UNICEF reported that over 500 children have been killed,[53][54] Another 400 children have been reportedly arrested and tortured in Syrian prisons.[55][56] Both claims have been contested by the Syrian government.[57] Additionally, over 600 detainees and political prisoners have died under torture.[58] Human Rights Watch accused the government and Shabiha of using civilians as human shields when they advanced on opposition held-areas.[59] Anti-government rebels have been accused of human rights abuses as well, including torture, kidnapping, unlawful detention and execution of civilians, Shabiha and soldiers. HRW also expressed concern at the kidnapping of Iranian nationals.[60] The UN Commission of Inquiry has also documented abuses of this nature in its February 2012 report, which also includes documentation that indicates rebel forces have been responsible for displacement of civilians.[61]
