The UN's envoy to Yemen, Martin Griffiths, on Tuesday urged armed groups in the country to silence their guns for a Ramadan respite to the gruelling civil war.
Mr Griffiths said the holy month offered an "opportunity for all of us to come together, think of those who are suffering, and overcome our differences".
His comments come amid revived efforts to end the civil war in Yemen, which pits the Iran-backed Houthi rebels against various Yemeni forces and a Saudi-led coalition.
“Yemen continues to go through hard times,” said Mr Griffiths.
“Ramadan teaches us endurance, empathy and perseverance. I call on the parties to silence the guns and allow Yemenis to observe the month in safety and dignity and put every effort towards achieving what Yemenis aspire for: a lasting and sustainable peace.”
The Saudi-led coalition intervened in the conflict in 2015 to restore a government ousted by the Houthis the previous year. Tens of thousands of people have bene killed in fighting that pushed the Arab world's poorest country to the brink of famine.
