Wildlife rangers in Zimbabwe say they have put the northern resort town of Kariba on full alert after rogue lions mauled two people to death. The National Parks and Wildlife Authority said fliers were being handed out in the town and volunteers were using a loudspeaker to caution townspeople on the dangers of lion attacks on the shores of Lake Kariba, a man-made hydroelectric dam popular for fishing and tourism. It said one man escaped from a lion attack on Tuesday, but the woman with him was savaged to death. An arm and the remains of a second corpse were found by rangers hunting for the lions. The authority warned people against walking at night and using footpaths through the bush as shortcuts.
