US Secretary of State John Kerry has pledged £143 million in new US aid for the humanitarian crisis in Yemen.
Kerry said the international response to Yemen's civil war had fallen short of the region's needs, and pledged a renewed political and security approach to resume talks.
The secretary of state said the new "fair and sensible" plan calls for a unity government and a transfer of heavy weapons from the Houthi rebel group to a third party.
The Houthis seized control of Yemen last January, prompting a Saudi-led military intervention.
More than 6,000 Yemenis have been killed in the conflict - more than half of whom were civilians.
Kerry said the UN envoy to Yemen will immediately begin a series of consultations with Yemeni parties.
