United Nations special envoy for Yemen Martin Griffiths gives a press conference on September 5, 2018, ahead of peace talks with the government and Huthi rebels in Geneva. - Yemen's Huthi rebels said on September 5, 2018 they were stranded in the capital Sanaa on the eve of United Nations-sponsored peace talks in Geneva with their government rivals. The Huthis said the UN had been unable to "secure authorisation" from a Saudi-led coalition backing the government for a plane to transport the rebel delegation and wounded insurgents out of the country, according to the Huthis' Al-Masirah TV. While the Huthis control Sanaa and much of northern Yemen, the coalition controls the country's airspace. (Photo by Fabrice COFFRINI / AFP)
