Why is the Yemen War not a major news story?

Its possible that a lot of people haven't heard of this because it's hardly been in the news but it's a brutal human catastrophe that rivals the Syria War in terms of its brutality and loss of life. Saudi Arabia is doing a lot of killing and they are armed with British and American weapons. Why is this not a major international news story?
