Medical aid, food supplies reach Yemen

UNICEF says vaccines cargo can't be one-off due to 'immense need'

SANAA, Yemen - The UN child agency said it has flown 1.9 million doses of vaccines to war-torn Yemen, its first delivery of humanitarian aid after 20-day military blockade from Saudi-led coalition.

Regional UNICEF director Geert Cappelaere described Saturday's shipment as a "very small step" at a time of immense need and warned that it must not be a one-off.
