Yemen's Houthi rebels have confirmed in writing to the UN secretary general their commitment to UN resolutions aimed at ending the country's conflict.
Houthi representatives pledge to adhere to a seven-point peace plan brokered by the UN during talks in Muscat, Oman.
The letter follows a verbal commitment to the resolutions issued last month.
The UN estimates nearly 4,900 people, including 2,355 civilians, have been killed in the conflict in Yemen.
Addressed to Ban Ki Moon, the letter commits to the seven principles, which include a ceasefire, the removal of armed militias from the cities and the return of the government to the capital, Sanaa.
