DEIR AL-BALAH, Gaza Strip (AP) — In just 25 days of war, more than 3,600 Palestinian children have been killed in Gaza, according to the strip’s health authorities. They were hit by airstrikes, smashed by rockets, burned by blasts and crushed by buildings. Among the dead were avid readers, budding journalists and infants too young to comprehend what was happening. The advocacy group Save The Children says more children were killed in Gaza in October than in all conflict zones around the world combined last year. With nearly half of the crowded strip’s 2.3 million inhabitants under the age of 18, children are the most vulnerable victims of Israel’s powerful airstrikes.
