Members of the media film as a ranger performs a post mortem on the carcass of a rhino after it was killed for its horn by poachers at the Kruger national park in Mpumalanga province August 27, 2014. Rhino poachers in South Africa now risk giving themselves away when they shoot thanks to a high-tech, gunfire-detection system being piloted in the country's flagship Kruger National Park. The stakes are high, for rhinos are being slain in escalating numbers for their prized horns, alarming both conservationists and the government since wildlife in South Africa is an important tourist draw.

Palestinians hit injured Israeli settlers, center, detained by Palestinian villagers in a building under construction near the West Bank village of Qusra, southeast of the city of Nablus, Tuesday, January 7, 2014. Palestinians held more than a dozen Israeli settlers for about two hours Tuesday in retaliation for the latest in a string of settler attacks on villages in the area, witnesses said. The military said the chain of events apparently began after Israeli authorities removed an illegally built structure in Esh Kodesh, a rogue Israeli settlement in the area. In recent years, militant settlers have often responded to any attempts by the Israeli military to remove parts of dozens of rogue settlements, or outposts, by attacking Palestinians and their property. The tactic, begun in 2008, is known as “price tag”. (Photo by Nasser Ishtayeh/AP Photo)
