The United Nations aid chief Stephen O'Brien has warned that Yemen is sliding deeper into humanitarian crisis and could face famine this year.
International charities and NGOs meeting in London have urged the world to stop ignoring the crisis.
Yemen, one of the poorest countries in the region, has been ravaged by war between the Houthi rebels and forces loyal to exiled government headed by Abd-Rabbu Mansour Hadi.
A Saudi-led coalition launched a military campaign against the rebels at the request of Hadi following his ouster as the president in 2015.
