KUWAIT CITY – Yemen’s warring parties began face-to-face peace talks on Saturday on “key issues” in a bid to end the conflict in the impoverished Arab country, the United Nations said. “All delegations are present. Key issues will be addressed,” Charbel Raji, spokesman for Yemen’s UN envoy Ismail Ould Cheikh Ahmed, told AFP about the negotiations taking place in Kuwait. Most of the meetings in talks which began April 21 have so far been confined to encounters between rival delegations Ould Cheikh Ahmed. More than 6,800 people have been killed and around 2.8 million displaced in Yemen since a Saudi-led coalition began operations in March 2015 against Iran-backed Huthi rebels, who seized swathes of territory including the capital Sanaa.
