Doctors Without Borders has said that its medics "treated at least 100 Palestinian children during the protests on the Gaza Strip this week".
According to director Jonathan Whittall, the children treated were seriously injured and will face lifelong difficulties as a result.
Plenty of them are less than 15-years-old and the majority of them were shot with live ammunition, many of the children require amputation and will be disabled for the rest of their lives.
In a statement released Monday night, after Israeli forces had shot and killed dozens of Palestinian demonstrators, Doctors Without Borders described the day's carnage as "unacceptable and inhuman".
"It is unbearable to witness such a massive number of unarmed people being shot in such a short time," the international medical relief group added.
