The Syrian Human Rights Committee (SHRC) has documented the killing of 1574 people during September 2015. The primary cause behind the deaths was the targeting of popular markets in Syrian cities and towns during peak times, in addition to clashes with the Syrian regime and with ISIS. The various executions committed by ISIS, international alliance bombing and Russian bombing, as well as mortar shell bombings by factions of the opposition were also a cause for deaths during the month.
SHRC also documented the death of 257 children, 152 women, and 55 people killed under torture in Syrian regime prisons and detention centres.
One hundred and thirty people were killed by ISIS during September, whilst 120 were killed by mortar shells from factions of the armed opposition on districts loyal to the regime. Thirteen were killed by bombing of the international alliance, 35 were killed by Russian war planes, 10 were killed by Kurdish militias, and 12 died to lack of nutrition and medicine in the besieged Eastern Ghouta, as well as the areas besieged by ISIS in Deir Ezzour.
The province with the highest number of deaths was Damascus and its suburbs, in which 461 were killed, followed by Aleppo in which 319 were killed, and then Homs in which 190 were killed.
In Deir Ezzour 167 were killed; 162 in Idlib, in Daraa 101 were killed and in Hama 58 were killed.
In Ar-Raqqah 37 were killed, and 36 in Al-Suwaida. Twenty-two were killed in Al-Hasaka, 17 in Latakkia, and four in Al-Quneitra.
