In the run-up to the event, Reuters photographers in countries around the globe took a series of portraits of women and their daughters. They asked each mother what her profession was, at what age she had finished education, and what she wanted her daughter to become when she grew up. They also asked each daughter at what age she would finish education and what she wanted to do in the future. The series of images offers an insight into the lives of women and girls around the world”. – Reuters. (Photo by Feisal Omar/Reuters)

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.

We’d come to sleep in cozy ger tents, the traditional yurt abode of the Mongolian steppe; sip mare’s milk tea; climb mountain glaciers; ride horses to an ancient battle site, and attend the annual Eagle Hunting Festival in Ölgiy...”. – Kathryn Kysar via The Star Tribune.
