A sniper from the Yemeni security forces watches over during a gathering in support of the Huthi-led parliament, in the capital Sanaa on August 20, 2016. Yemen has been hit by unrest since the Huthi rebels and allied loyalists of former president Ali Abdullah Saleh overran the capital Sanaa in September 2014. The violence increased after a Saudi-led Arab coalition launched a military campaign in March last year to help shore up the government of President Abedrabbo Mansour Hadi. / AFP / MOHAMMED HUWAIS (Photo credit should read MOHAMMED HUWAIS/AFP/Getty Images)
