So says the United Nations, highlighting the grave consequences of a conflict that has left 18.8 million people in need of humanitarian or protection assistance, including 10.3 million who require immediate assistance to save or sustain their lives.

The war and its economic effect are driving the largest food security emergency in the world: more than 17 million people in Yemen are currently food-insecure, of whom 6.8 million are severely food-insecure and in need of immediate aid.
The conflict has been going on for years but became especially violent in March 2015 after the involvement of a Saudi-led coalition.
More than 10,000 people have been killed and three million displaced from their homes since February 2014, according to the UN.
