Yemen has been engulfed in an armed conflict between the government forces, led by President Abdrabbuh Mansour Hadi, and the Houthi rebels for several years.
Since March 2015, the Saudi-led Arab alliance, working in cooperation with Hadi's forces, has been conducting air, land and sea operations against the rebels, who control the capital of Sanaa and large areas in northern and western Yemen.
