UN: 74 children killed as fighting intensifies

More than 100,000 people in Yemen have fled their homes in search of safety, and at least 74 children have been killed since fighting in the country intensified almost two weeks ago, according to the United Nations' children's agency.

UNICEF said the violence has disrupted water supplies in areas of southern Yemen and that sewage is overflowing in some locations, raising the risk of widespread disease.

Hospitals are struggling to treat large numbers of wounded with insufficient supplies, and some medical facilities have come under attack, the agency said. It said at least three health workers, including an ambulance driver, were killed in attacks.
