TOPSHOTS Tribal gunmen loyal to the Shiite-Huthi movement walk holding their weapons during a gathering against the Saudi-led intervention in the country in the Bani al-Harith area, north of the capital Sanaa, on August 6, 2015. Yemen has been riven by violence since a Saudi-led coalition launched air strikes against Huthi rebels earlier this year after they and troops loyal to ousted president Ali Abdullah Saleh approached Aden after seizing Sanaa in September.
