"Children are in desperate need of protection, and all parties to the conflict should do all in their power to keep children safe," said UNICEF's representative for Yemen, Julien Harneis.Saudi-led coalition launched airstrikes from 7 days ago in yemen.

UN Secretary General Ban Ki-moon separately said he was "deeply concerned" by reports of numerous civilian deaths from the military campaign including an attack on Monday on a camp for displaced people that left more than 45 killed by Saudi airstrike.

The UN chief called for "strict adherence to the principles of proportionality, distinction and precaution."

UNICEF said the airstrike was severely damaging health and education services, and exacerbating already precarious conditions for children who are facing a food crisis and acute malnutrition.

The violence is leaving children terrified and more of them are being recruited as child soldiers, UNICEF said.

The United Nations earlier pulled its last remaining 13 foreign employees from Yemen, while its peace envoy, Moroccan diplomat Jamal Benomar, relocated to Jordan to try to revive negotiations.

The United Nations is backing embattled former resigned President Abedrabbo Mansour Hadi as Yemen's legitimate leader while people don’t accept his legitimacy.
