Tribal gunmen loyal to the Huthi movement brandish their weapons on March 26, 2015 during a gathering in Sanaa to show support the Shiite Huthi militia and against the Saudi-led intervention in the country. Warplanes from a Saudi-led Arab coalition bombed Huthi rebels in support of Yemen's embattled president, as regional rival Iran warned the intervention was a 'dangerous' move.
