Garamba National Park in the Democratic Republic of Congo is under constant assault by renegade Congolese soldiers, gunmen from South Sudan and others. And this is just a slice of the carnage: international wildlife regulators say 20,000 elephants were killed just in Africa in 2013. The Johannesburg-based African Parks group, which manages the park, said that since mid-May, the 5,000 square kilometer (1,900 square mile) Garamba National Park in Congo, which was established in 1938, has faced an onslaught from several bands of poachers who have already killed 4 percent of its elephant population. "The situation is extremely serious," Garamba park manger Jean-Marc Froment said in the statement. "The park is under attack on all fronts." A 2012 census found just 2,000 elephants in Garamba Park, down from 20,000 in the 1960s.
