From house breaking in Johannesburg to hippos on the loose in Tbilisi to rioters attacking a policewoman in Burundi, Reuters photographers tell the story behind some of the most iconic pictures of the year. Here: Protesters drag a female police officer accused of shooting a protester in the Buterere neighbourhood of Bujumbura, Burundi, May 12, 2015. Goran Tomasevic: Protesters started throwing stones at a group of police, who then started to run away. The policewoman in the photo, Medikintos Inabeza, 33, got left behind and then some protesters started to push her, saying that she had shot a female protestor in the stomach with an AK47 rifle. I didn't see anything of that. There were 5 or 10 protesters pushing the policewoman at first, then others came and joined in. Up to 20 or 30 protesters were surrounding her at one point. The protesters kicked and beat her very badly; I also saw a couple of knives. I thought they were going to kill her... (Photo by Goran Tomasevic/Reuters)

“Snowflake (c. 1964 – November 24, 2003) was an albino gorilla. He was the only known albino gorilla so far, and the most popular resident of the Barcelona Zoo in Catalonia, Spain. Originally named Nfumu Ngui in Fang language ("white gorilla") by his captor, he was then nicknamed Floquet de Neu (Catalan for little snowflake) by his keeper Jordi Sabater Pi. On his arrival to Barcelona where he was given an official reception by the then Mayor of Barcelona, Josep Maria de Porcioles, in November 1966, he was called Blancanieves (“Snow White”) in the newspaper Tele/Exprés. But he became famous with the name given to him by Sabater when National Geographic Magazine featured him on the main page in March 1967, with the English name Snowflake. This name spread among the press (Stern, Life, Paris-Match) and was later translated to Spanish as Copito de Nieve. Sabater himself called the gorilla Floquet or Copi, and in the later years Nfumu. The asteroid 95962 Copito, discovered by Catalan astronomer J. Manteca, is named in his honour”.
