The group's annual report measures perceptions of corruption due to the secrecy surrounding most corrupt dealings. Two thirds of the 168 countries assessed were identified as having a serious corruption problem. Somalia, which has been mired in conflict since civil war broke out in 1991, ranks bottom of the list.

In this photo taken Friday, September 4, 2015, tourists Sarah and John Scott from Worcester, England, take a step back as a male silverback mountain gorilla from the family of mountain gorillas named Amahoro, which means “peace” in the Rwandan language, unexpectedly steps out from the bush to cross their path in the dense forest on the slopes of Mount Bisoke volcano in Volcanoes National Park, northern Rwanda. Deep in Rwanda's steep-sloped forest, increasing numbers of tourists are heading to see the mountain gorillas, a subspecies whose total population is an estimated 900 and who also live in neighboring Uganda and Congo, fueling an industry seen as key to the welfare of the critically endangered species as well as Rwanda's economy.

Life reconstruction of the new oviraptorosaurian dinosaur species Anzu wyliei in its 66 million-year-old environment in western North America as seen in an undated handout illustration by Mark A. Klinger, Carnegie Museum of Natural History.

Trees grow through the windshield of a 1937 Chrysler Imperial as it sits at Old Car City, the world's largest known classic car junkyard Thursday, July 16, 2015, in White, Ga. Over 4,000 classic cars decorate 32 acres of forest which have been turned into a junkyard museum by owner Walter Dean Lewis. The two grew up playing in the cars on the lot which started as a general store selling auto parts in 1931 by Lewis' parents. Lewis stopped selling parts about six years ago when he realized he could sustain the business more as a museum, charging $15 for visitors just looking, and $25 for photographers. Many of the cars have never moved in over 30 years and in some cases, trees now grow through them, even lifting some off the ground. (Photo by David Goldman/AP Photo)
