A Zimbabwean man was killed while trying to rescue his friend from attacking crocodiles in northwest Zimbabwe, a fishing club said Wednesday. The National Anglers' Union said that Frank Trott, aged in his 70s, died after trying to rescue a friend paddling along the shoreline at Charara fishing camp. His friend survived but sustained wounds to his midsection and buttocks. The dead man was dragged away by a giant crocodile after going to assist his friend, said Mike Brennan, head of the fishing group. The friend, aged in his 40s and a fellow farmer with experience in the African wilderness, was treated for his wounds.
