UN Secretary-General Antonio Guterres has assured Yemen’s leader that the world body will remain impartial in efforts to resolve the country’s conflict, rejecting accusations that its envoy was siding with rebels. The pledge came in a letter from Guterres to President Abedrabbo Mansour Hadi, who had accused the UN special envoy to Yemen of impartiality. “I would like to assure you that every effort will be made to maintain the impartial stance that is expected of the United Nations,” while implementing a ceasefire agreement, Guterres said in the letter seen by AFP on Sunday. In his own letter addressed to Guterres, Hadi accused envoy Martin Griffiths of “providing the Huthi militia with guarantees to stay in Hodeida and its ports under the umbrella of the UN”. “I can no longer accept these offences by your special envoy which threaten chances to find a (lasting) solution,” Hadi said.
