More than 5,000 people, including children, were killed in Syria during the holy month of Ramadan, which ended with Eid al Fitr on Friday, according to the Syrian Observatory for Human Rights.
The UK-based monitoring group, which highlights atrocities in Syria by the Syrian regime, Isis, and rebel groups, said that 1,220 civilians, including 224 children and 222 women were among those killed in the last one month, mainly from regime and coalition airstrikes.
Documenting the death toll in Syria during the month of Ramadan, the monitoring group said that more than 500 people, including over 100 children, were killed in airstrikes conducted by the Syrian regime forces.
69 civilians, including 22 children and 7 women, were wounded on the last day of Ramadan alone in airstrikes by Syrian forces across the country, the group said.
Apart from the airstrikes, civilians in Syria also faced Isis brutalities, with 285 people, including 29 children and 60 women, executed by the terror group, according to the Syrian Observatory for Human Rights (SOHR).
Most of the Isis executions occurred in Kobani, according to the group.
More than 200 people were also killed in the fighting between regime forces and rebel groups, mostly due to shelling and explosion of IEDs.
Hundreds of fighters of groups such as the Isis, Jabhat al- Nusra and the Kurdish YPG were also killed.
Non-Syrian fighters part of Isis and other terror and rebel groups in the country suffered the heaviest casualties, with SOHR documenting 1,665 deaths of foreign fighters in Syria during Ramadan.
Thousands of Syrians have been killed over the last few years in the fighting between the regime forces and rebel groups, while Isis has executed over 3,000 people in Syria since forming a caliphate in the country last year.
"SOHR demanded US Security Council to move urgently in order to stop the massacres committed against the Syrian people every day, and to issue a binding resolution to refer the file of war crimes and crimes against humanity to specialised international courts in order to punish the murderers of Syrian people," the monitoring group said in its article on Saturday.
