Members of the Iraqi Counter Terrorism Service (CTS) forces look at the positions of Islamic State militants during clashes in western Mosul, Iraq, May 15, 2017. Danish Siddiqui: "In May, I was accompanying a senior commander of Counter Terrorism Service, an elite Iraqi security force trained by the U.S., during the battle to take control of Western Mosul. We arrived at a small house on the frontline after walking through holes in the walls between homes. Islamic State snipers were firing a few hundred meters away. The people who once lived there departed quickly, leaving clothes and toys scattered across the floor. The next inhabitants left hollow shell casings. The CTS had taken over the house a day ago. The curtain was a bed sheet. They stood behind it to identify enemy snipers and watch one of their own. It's a quiet picture that tells of even the most uneventful of moments on the front, when nothing may happen, and everything is possible."

A tightening siege has pushed people to the verge of famine in the eastern suburbs of Damascus, residents and aid workers say, bringing desperation to the only major rebel enclave near the Syrian capital. At two and a half years old, Hala al-Nufi weighs less than five kilos (12 pounds). She suffers from a metabolic disorder, but a lack of adequate food has made the case extreme. Hala, her eyes hollow and her translucent skin stretching over her tiny bones, had gotten sicker in recent months, her parents said. They worry she will not survive the siege.
