An Afghan girl carries water on her back as she climbs a hill in Kabul, Afghanistan February 20, 2017. A growing population is straining water supplies in Afghanistan's capital, forcing those who can afford it to dig unregulated wells ever deeper to tap a falling water table. Finding water in arid Afghanistan is virtually always a challenge, but a drop in the groundwater level in Kabul caused by overuse and drought is making it even more difficult for residents, especially the poor.

Being able to look at this world in a different light is the main thing that distinguishes a true artist from a common person. We can clearly see that Lucas Levitan is a true artist despite the crude drawings that he makes. By hunting through thousands of photos that people post on Instagram, he finds the ones that might have a completely different, surprising, and comical theme. For example, a sensual photo of lady’s eyelashes is transformed into a scene in which a farmer is harvesting his crops. This is imagination at its finest, which is why the art works of Lucas Levitan are so interesting to look at. (Photo by Lucas Levitan)

Leaves and forest foliage claim abandoned motors at makeshift car graveyards. German photographer Dieter Klein travels the world to find vintage automobiles left to rust in leafy forests and fields.

A humane society have drafted in Star Wars characters to help find adoptable animals new homes. The Ottawa Humane Society in Ontario, Canada, used the recognisable cosplay figures to adorably interact with the likes of dogs, cats and guinea pigs. Photographed by Rohit Saxena, the series featured a stormtrooper, a Tusken Raider and Garindan. Those photographed were members of the 501st Capital City Garrison, a Star Wars costuming group in Eastern Ontario. Here: a Tusken Raider with a cat. (Photo by Rohit Saxena/Caters News)

Iain Blake is an amateur photographer that has gained his popularity on the Internet thanks to his photoset of “Stone Footprints”. By finding the right stones and perfectly arranging them, Iain was able to make a number of very appealing pictures. For some reason, these “footprints” look adorable. It could have something to do with the cartoony appearance that they have. In our opinion, the finest photo out of this whole set is the one with a large footprint and a smaller one on top of it, as if a child has stepped into the footprint left by his or her parent.

Throughout the course of the long war in Afghanistan, Coalition troops have relied on thousands of military working dogs to help keep them safe, and make their jobs easier. The dogs are trained to detect explosives, to find illegal drugs, to search for missing comrades, or target enemy combatants. Not only are they active on the front lines, but behind the lines they serve as therapy dogs, service dogs, and loyal companions. They also share the same risks as the ground troops, suffering injuries and sometimes death on the battlefields. Gathered here are images of these dogs and their handlers in Afghanistan and back home, from over the past several years, part of the ongoing series here on Afghanistan.
