The United Nations named an outgoing Dutch minister its humanitarian coordinator for Gaza on Tuesday following last week's watered-down Security Council resolution which called for aid to be delivered to the strip "at scale."Sigrid Kaag's appointment comes as the people of Gaza face a dire humanitarian emergency, with aid slowed to a trickle by Israel's continued bombardment of the densely populated coastal strip.She will start work on January 8, the UN said in a statement.
