The conflict has so far left about 4,500 people dead and thousands of others wounded, the UN says. Local Yemeni sources, however, say the fatality figure is much higher.
The United Nations has repeatedly voiced concern over the rising number of civilian casualties in the Saudi military aggression against the impoverished Arab country.
