At least 224 people were killed during the first week of Ramadan in conflict-ridden Syria, according to the Syrian Observatory for Human Rights. The U.K.-based monitor said Monday that the victims included 67 children and 28 women who were killed between June 6 and 12.

“We in the Syrian Observatory for Human Rights renew our condemnation of the international community for its continued terrifying silence about the crimes committed against the Syrian people,” the monitor said in a statement. “We repeat our call for sending the war crimes and crimes against humanity committed in Syria to the International Criminal Court.”

The deaths include the 148 civilians killed in the clash between Syrian and Russian warplanes where explosive barrels were dropped by helicopter. During this one-week period, the Islamic State group, also known as ISIS, also executed one man in addition to 12 persons including three children and a woman who were killed in shelling by rebels and snipers from the extremist group, the monitor said in its report.

On Sunday, airstrikes conducted in the northwestern Syrian city of Idlib killed at least 40 civilians. According to Al Jazeera, while several monitoring groups and Turkish authorities blamed Russia for the strikes, the latter has denied any wrongdoing.

The Syrian Observatory for Human Rights report comes at a time when hundreds are fleeing the country that is witnessing a multisided war since March 2011.
