More than 6 billion people live in countries where serious levels of public sector corruption are fueling inequality and exploitation, according to Transparency International's 2015 index of perceived public sector corruption. 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.

Two daredevil photographers have risked their lives to become the first people to capture the explosive moment fiery lava crashes into the sea – while in the water themselves. Fearless duo Nick Selway, 28, and pal CJ Kale, 35, brave baking hot 110F (43,3C) waters to snap the amazing images – standing just feet away from scalding heat and floating lava bombs. Using a simple protective casing around their cameras, and donning just swimming shorts and flippers, they bob up and down with the water as the surf washes over their heads.
