Meanwhile, UNICEF's resident representative in Yemen, Meritxell Relano, has called for an end to Saudi Arabia's war on Yemen and continued massacring of children.

"In the recent attack in Sa�ada, I have visited at least 13 children that have injuries and I hope that they are good to go very soon and back to play, and play football, and back to their normal lives because this has been a very shocking attacks, terrifying, which will leave them not only physical injuries but also psychological injuries," Relano added.
