Aid groups use land routes to deliver humanitarian relief to Iran

GENEVA, April 14 (Reuters) - International humanitarian groups said on Tuesday they had sent emergency relief through overland routes to Iran, some of their first deliveries of aid since U.S.-Israeli strikes began in late February.Aid workers say needs are high in the wake of six weeks of strikes, but stocks of emergency humanitarian supplies became stuck in Dubai warehouses as shipping and air routes were blocked by the expanding conflict.
