Aid groups are sounding the alarm over a spike in child malnutrition in war-torn Gaza, as Britain, France and Germany prepare to hold an emergency call Friday on the deepening humanitarian catastrophe.

Doctors Without Borders, also known by its French acronym MSF, reported that 25% of children and pregnant or breastfeeding women screened at its clinics last week were malnourished – just a day after the United Nations warned that one in five children in Gaza City is going hungry.

With fears of mass starvation mounting, the three European powers are set to push for an urgent cease-fire and weigh steps toward Palestinian statehood.

“I will hold an emergency call with E3 partners tomorrow to discuss immediate action to stop the killing, get food to those in desperate need, and lay the groundwork for lasting peace,” British Prime Minister Keir Starmer said.

The call comes after hopes of a new cease-fire in Gaza faded Thursday when Israel and the U.S. withdrew from indirect negotiations with Hamas in Qatar.
