Rachel Accurso has made a name for herself as one of the internet’s most popular children’s entertainers, but she’s also one of the most outspoken voices for the rights of children everywhere — especially in the besieged Gaza Strip.

Now, with the release of a report from the UN-formed Independent International Commission of Inquiry saying Palestinian children have been deliberately targeted and killed by Israeli security forces, she has just one question for world leaders: “Where have you been?”

“Did you not see these kids as kids because of where they were born? Did you not think the 20,000 kids that were killed and the countless others under the rubble who died of starvation and other causes that would be so simple to treat,” asked a visibly upset Accurso in a video shared to her Instagram page.

She questioned whether those in positions of power realised the children of Gaza “had beating hearts like your kids”. She quoted parts of the report saying 151 children had died of starvation and mentioned “the deliberate targeting of children”, including an incident in which a breastfeeding baby was killed by quadcopter while inside a tent.

She wondered aloud what the leaders of the world had to lose by speaking up for what is right and asked how they were able to “go to sleep at night knowing you didn’t say anything”.
