A herd of elephants has trampled to death a police officer in a central Vietnamese jungle. The victim and two other men went into the jungle on Saturday to look for apricot trees. Huynh Trung Luan, the director of the elephant conservation center in Daklak Province, said more than 20 wild elephants attacked the men as they returned home that night. Two of the men escaped unhurt, but the 42-year-old policeman was found dead on Sunday morning. Luan said the herd became more aggressive after two of its members were killed by villagers in August.—AP
