By Utpal Parashar Eighteen wild elephants have been killed, most probably due to lightning, in Assam’s Nagaon district, officials informed on Thursday. “The incident took place at Bamuni area of Barhampur on Wednesday. Our officials got to know about it on Thursday. Teams of forest and veterinary officials are at the spot to take stock of the tragedy,” Nagaon, deputy commissioner Kavitha Padmanabham said. The deaths took place in an area with small hillocks and forests. Officials suspect the elephants, which were part of a herd, were staying close to each other when lightning struck. While four bodies were found at the bottom of a hillock, 14 others were found at the top.
