A herd of wild elephants again encroached on human settlements in Trumon Timur sub district, South Aceh District, where they damaged commercial and food crop plantations, ANTARA reported. "The problem of elephant attacks is continuing. The villagers have been restless for more than three weeks due to the behavior of the protected animals," T. Masrizar, a resident of Trumon, said here on Monday. Meanwhile, Naca Village Head Ramli Hajnur said a herd of four wild elephants had attacked and damaged tens of hectares of oil palm and food crop plantations in the village located in Trumon Timur sub district. "Wild elephants, three or four of them, have often been spotted in residential areas. They cause fear and panic among the villagers," Ramli Hajnur said. Earlier, Trumon Timur Sub district Head Lahmuddin said a herd of 16 wild elephants had attacked and damaged hundreds of hectares of oil palm and food crop plantations as well as rice fields. Officers of the Natural Resources Conservation Agency (BKSDA) some time ago managed to tame two elephants last January and thereby stop a conflict between humans and the giant animals.
