"More than half a million children in Yemen face life-threatening malnutrition as a risk of famine grows, a senior official of the U.N. Children's Fund (UNICEF) said on Friday." "Yemen, which imported 90 percent of its food before the crisis, is subject to a Saudi-led blockade imposed on commercial vessels, which are inspected by a U.N. verification mechanism. "We are allowed small passages of goods where the papers are clear," Khan said. "We have been unable to sufficiently replenish medical supplies." The lack of fuel imports is preventing mills from grinding grain, she said." (thanks Amir)
