Food aid in a warehouse on the frontlines of the Yemen war is at risk of rotting, the UN said yesterday.  The Red Sea Mills silos, located in the western port city of Hodeida, are believed to contain enough grain to feed several million people for a month. But the granary has remained off-limits to aid organisations for months. Hodeida, and its food silos, have been in the hands of Yemen's Huthi rebels since 2014, when the insurgents staged a takeover of large swathes of Yemeni territories.
