(CNN) Two years on and the conflict in Yemen shows little signs of abating. A Saudi-led coalition of regional states and Houthi rebels continue to bombard one another, while terrorist groups operate unhindered -- leaving millions of civilians in the crossfire.
The conflict has devastated Yemen's economy and spurred a humanitarian crisis, with civilians unable to afford shelter, food or medicine, and aid groups powerless to reach vulnerable communities.
