A doll, placed by stranded Iranian migrant protesters, hangs from barbed wire in front of Madedonian police at the Greek-Macedonian border near to the Greek village of Idomeni November 29, 2015. The protesters were demonstrating against what they say is the closure of the border for Iranian migrants. According to the demonstrators, the hanging toys and dolls represent the outcome of being unable to return, if they are sent back to Iran. (Photo by Yannis Behrakis/Reuters)

This is the remarkable moment a group of skydivers performed a world record breaking feat in honour of their friend who died while skydiving. Known as a “Bigway”, the daring jump involves 57 people holding hands in a predetermined design as they hurtle towards the ground, head first. After making the first shape, the group then break away before coming back together to form a second shape all in a single skydive. Captured using a GoPro camera by Alaskan skydiver, Ben Nelson, 36, the topsy-turvy footage shows the adrenalin junkies soaring through the air at around 160mph before banding together twice in mid-air, making the stunt a world first.

Non-EU Serbia's frontier with Hungary, which is in the bloc's passport-free Schengen zone, has become a major crossing point for the huge numbers of migrants entering the EU.

Breath of an Arctic fox by Marco Gaiotti, Italy. Marco was watching this little Arctic fox as it incessantly called another nearby. Gradually he noticed the fox’s wet breath was quickly freezing in the air after each call. It was late winter in Spitsbergen, Svalbard, and the air was -35C (-31F). Photographing Arctic foxes is often frustrating, as they are normally running around fast in search of food, but this one was very relaxed and let Marco get close enough to focus on it, with the light glowing perfectly in the background.
