15 images show the humanitarian crisis unfolding in Puerto Rico

Hurricane Maria made landfall as a Category 4 storm in Puerto Rico on September 20, devastating the US island territory that an estimated 3.4 million US citizens call home.

But beyond the images of destroyed buildings or massive floods, a humanitarian crisis is unfolding on the island. Much of Puerto Rico was without electricity days after the storm pushed past the island. Food, clean drinking water, and other vital resources have been scarce.

As stories of the dire conditions emerged, humanitarian aid is slowly trickling in with the federal government's help. President Donald Trump has also announced that he will visit the island on Tuesday.
