ISRAELI air strikes killed up to 10 times as many civilians during its 11-day bombardment of Gaza this year than in the Israeli military’s (IDF) eight-year bombing campaign of Syria, new research reveals.

Between 151 and 192 civilians were killed between May 10 to 21 when the IDF began striking Gaza, according to report published today by Airwars, a non-profit group monitoring civilian deaths from air strikes.

“Over a third of reported civilian victims of Israeli strikes were children. Most were killed while with their families, in the evenings or at night. A further 612 to 847 Palestinians were reported injured,” the report says.
