Warring sides must let more aid get through to 8.4 million people who are 'a step away from famine' in Yemen, a senior UN official said on Monday. A Saudi-led military coalition fighting the Iran-aligned Houthi movement in Yemen's civil war blockaded ports last month after a missile was fired towards Riyadh. Jamie McGoldrick, the Humanitarian Coordinator for Yemen, said the blockade has since been eased, but the situation remained dire.
