Nearly 3,000 children in southern Gaza are at risk of dying after their treatment for malnutrition was stopped, according to the UN's children's organisation Unicef.
People's access to healthcare continues to be affected by the violence and people being forced to flee, the organisation stated in a press release.
The number of children at risk corresponds to around three-quarters of the 3,800 children who were estimated to receive life-saving care in southern Gaza before the situation in the southern border town of Rafah deteriorated.
"Horrific images continue to emerge from Gaza of children dying in front of their families' eyes due to the ongoing lack of food... and destruction of healthcare services", said Adele Khodr, Middle East chief for Unicef, according to the press release.
There is also a risk that more vulnerable children will become malnourished. Access to humanitarian aid in southern Gaza has decreased significantly, while the situation has slightly improved in the north.
"Our warnings about increased deaths among children dying from a combination of malnutrition, dehydration, and preventable diseases should have mobilised immediate action to save children's lives, and yet this devastation continues", said Adele Khodr.
