"The true toll of this conflict is likely to be far higher," said the children's agency UNICEF about the casualties of the world's worst humanitarian crisis.
"Thousands of children have lost their lives, and hundreds of thousands more remain at risk of death from preventable disease or starvation," said UNICEF executive director Catherine Russell.
About 2.2 million Yemeni children are acutely malnourished, one-quarter of them aged under five, and most are at extreme risk from cholera, measles and other vaccine-preventable diseases, UNICEF said.
Hundreds of thousands have died since, either as a result of fighting or indirectly through unsafe drinking water, disease outbreaks, hunger and other impacts, AFP reported.
The agency's latest numbers confirm 3,774 child deaths between March 2015 and September 2022.
UNICEF appealed for $484.4 million in funding to tackle the humanitarian crisis.
