Parties to the Yemen peace talks have a "moral and political" responsibility to end the conflict, the UN Secretary-General urged on Sunday.
Speaking in Kuwait where the negotiations were being hosted, Ban Ki-moon expressed concern about the worsening situation back in the war-torn country.
He also met with the Gulf nation's top authorities and thanked them for their ongoing support to the process.

Time is not on the side of the Yemeni people, the Secretary-General warned delegates in Kuwait representing the country's main opposing blocs.
The situation grows worse every day and the longer the conflict endures the more time it will take the country to recover, the UN chief noted.
"There is an alarming scarcity of basic food items. The economy is in a precarious condition. Whilst the cessation of hostilities is mostly holding, there have been serious violations causing further casualties and suffering amongst the civilian population, including children. This worrying situation gives you, the delegations to the Yemeni talks, a very serious responsibility. You have a moral and political responsibility."
Mr Ban called on the parties to return to the transitional process initiated in 2011.
Civil war between government forces and Houthi rebels intensified more than a year ago, and more than 2.4 million have been forced from their homes.
