A Yemeni soldier, pictured through a vehicle's windscreen, which was damaged by a bullet, gestures out of the window, in Marib, Yemen October 15, 2015. Marib is a city that is heavily armed even by the standards of Yemen, where the ready availability of weapons helped start civil war and is now preventing anyone coming out on top. Yemenis often say there are three guns for every person, a boast that has become an urgent concern in a country where the United Nations says the humanitarian situation is "critical".

Michael Grant, 28, “Philly Jesus”, carries a 12 foot cross 8 miles through this blighted area of North Philadelphia towards LOVE Park in Center City as part of a Christmas walk to spread the true message of the holiday in Philadelphia, Pennsylvania December 20, 2014. As many as a half dozen others joined him for numerous miles as he trekked southward down Broad Street. Some shouted “Praise Jesus!” and “Thank you for doing this!” at the sight. Nearly everyday for the last 8 months, Grant has dressed as Jesus Christ, and walked the streets of Philadelphia to share the Christian gospel by example. He quickly acquired the nickname of “Philly Jesus”, which he has gone by ever since. (Photo by Mark Makela/Reuters)

A girl holds her brother in her arm as black smoke rises after an oil well set on fire in the center of al-Kayyara town to the south of Daesh terror organization-held Mosul in Iraq on October 25, 2016. The oil well in the center of al-Kayyara town, which was set alight by retreating Daesh militants in advance of the Iraqi army's takeover of the town on August 24, 2016 has still not entirely been put out. The raw petrol which is still alight is creating black clouds above the city. The residents and wildlife beneath this polluting smoke cloud may find their health at risk. The effects of the fire in the town center on unprotected civilians' health can easily be seen on the hands and faces of children playing on the street.
