UNITED NATIONS — The United States is proposing an urgent mediation mission to help resolve Ukraine’s crisis.

U.S. Ambassador to the U.N. Samantha Power told reporters Friday that the United States wants mediators who will be “seen as independent, credible.”

She suggested U.N. official Robert Serry could be part of the mission. Serry was the Netherlands’ first ambassador to Ukraine.

She also said that the Organization for Security and Cooperation in Europe had experts who would be seen as credible.

British U.N. Ambassador Mark Lyall Grant later said that such a mediation mission would not require the blessing of the U.N. Security Council. Russia has a council veto and could block action there.
