The article discusses the devastating impact of the ongoing armed conflict in Gaza on children's health and well-being. Gaza, a densely populated area under Israeli blockade and occupation, has been the site of intense fighting since October 7, 2023, resulting in significant casualties, including a high number of children. The conflict has led to widespread destruction of infrastructure, including schools and healthcare facilities, and has disrupted essential services such as food, water, and electricity. The international community has a responsibility to protect children from the effects of war, and the article highlights six grave violations against children under international humanitarian law, including the killing and maiming of children, abductions, attacks on schools and healthcare facilities, and denial of humanitarian access. The authors emphasize the immediate and long-term health consequences for children, including physical injuries, psychological trauma, and increased vulnerability to diseases. They call for an immediate and permanent ceasefire, the implementation of monitoring mechanisms to hold parties accountable, and urgent action to address the humanitarian crisis in Gaza. The article also provides recommendations for the child health community to advocate for children's rights and support their recovery.The article discusses the devastating impact of the ongoing armed conflict in Gaza on children's health and well-being.
