The conflict between Saudi-backed forces and Houthi rebels in Yemen, which has led to the world’s worst humanitarian crisis, has captured growing international attention.

An important catalyst appears to have been the Oct. 2 killing of Jamal Khashoggi, a dissident Saudi journalist, by Saudi agents in the kingdom’s Istanbul Consulate. This focused scrutiny on Saudi Arabia’s behavior in other parts of the world.

In-depth reporting by The New York Times has detailed a harrowing humanitarian crisis in Yemen. Secretary of State Mike Pompeo this week called for a cessation of hostilities between the warring parties in Yemen, a call echoed by his British counterpart, Jeremy Hunt.

We have been documenting the devastation in Yemen since the beginning of the conflict in 2015, and in October the reporter, Declan Walsh, and the photographer, Tyler Hicks, traveled to the country to provide a closer look. Their coverage has further driven the conversation.
