The intervention in support of Yemen's President Abedrabbo Mansour Hadi that began on March 26 2015 has yet to deal a decisive blow to the Huthi rebels and their allies, who still control Sanaa and key parts of the country. The Islamic State group and Al-Qaeda have exploited the chaos, widening their footholds in the south and carrying out deadly attacks, mostly against forces loyal to Hadi. The UN says about 6,300 people have been killed in the conflict since the coalition launched its campaign, more than half of them civilians. / AFP / Simon MAINA        (Photo credit should read SIMON MAINA/AFP/Getty Images)
