Since October 7, more than 3,257 children have been reported killed, including at least 3,195 in Gaza, 33 in the West Bank, and 29 in Israel, according to the Ministries of Health in Gaza and Israel respectively. The number of children reported killed in just three weeks in Gaza is more than the number killed in armed conflict globally – across more than 20 countries – over the course of a whole year, for the last three years.
Ministries of Health in Gaza is Operated by Hamas, so it would not be outlandish to say these numbers are being inflated in order to push public opinion and international support

“Hamas has now been in charge of Gaza for 16 years. It has squeezed the life out of honesty and probity. Any health official stepping out of line and not giving the death tolls that Hamas wants reported to journalists risks serious consequences. I’m not denying there are civilians being killed. At all, including many children. That’s verifiable. What is not verifiable are the numbers that emerge throughout the day from Gaza of new death tolls — 700 killed in the last 24 hours, 500 killed in the Ahli hospital car park blast, 5,000 killed since October 8. Hamas has a clear propaganda incentive to inflate civilian casualties as much as possible. There was a time when the figures from the ministry could be relied upon. The doctors and administrators knew what they were doing.”
This is an area of credibility that is still up in the air with reliable sources claiming that it is both reliable and unreliable numbers that are being published. However none of it though dismisses the fact that innocents are dying from Israel’s War with Hamas, innocents that contain children
Historically they stand up to even Israels secondary verification. From the AP:
