The well-being of the Yemeni people "remains of utmost importance" as they face "an unspeakable humanitarian crisis."
That's according to UN Spokesperson Stephane Dujarric, briefing reporters at UN Headquarters in New York on Monday.
Over the weekend, reported airstrikes killed at least 12 civilians, including women and children.
Matt Wells has the details.
The UN Humanitarian Coordinator for Yemen, Jamie McGoldrick, expressed deep concern over the airstrikes on a house and a private vehicle, and said these latest incidents were being investigated by the UN Human Rights Office.
For more than two years, a Saudi-led coalition, including fighter planes, has been battling Iranian-backed Houthi rebels for control of the country.
Mr McGoldrick said that all parties to the conflict continued to show a disregard for the protection of civilians, and he urged fighters to uphold their responsibilities under international law.
Suspected cholera cases have topped 400,000 in the country, while 20 million require humanitarian assistance, making it the world largest food-security crisis.
Here's UN Spokesperson Stephane Dujarric:
"All of the components of the UN in Yemen will continue to work with all the parties so as to bring some relief to the people of Yemen as they face an unspeakable humanitarian crisis. It is important the international community not lose sight of the plight of the millions of vulnerable Yemeni men, women and children. Their well-being remains of utmost importance."
Mr Dujarric also provided an update on UN agencies' ability to access fuel for humanitarian operations.
He said government assurances had been given that fuel will be moving this week, from government-controlled Aden to the capital, Sana'a, where Houthi rebels currently hold.
He said authorities had also been asked for a plan to ensure regular delivery of aviation fuel for UN operations.
