UNICEF calls on Yemen's warring sides to stop impeding aid

A senior official in the U.N. children's agency says the number of severely malnourished children in Yemen has doubled in three years of civil war, from 200,000 in 2015, and that an additional half a million boys and girls can no longer go to school.

Regional UNICEF director Geert Cappelaere called Sunday for an end to a "brutal war on children" in Yemen —a proxy battle between rivals Saudi Arabia and Iran.

Cappelaere says both sides have blocked or delayed humanitarian aid shipments, including solar equipment and fuel needed to improve access to clean water and fight an outbreak of cholera and diarrhea that affected more than 1 million Yemenis last year.

He says that time, energy and money was wasted "for discussions that should never happen" about aid deliveries.
