Three elephants have been killed by poachers in Simlipal Tiger Reserve, Orissa. The pair of tusks missing from one of the elephants pointed to the fact that this is the work of ivory traders. It appears that the elephants had been poisoned. Conservationists have expressed concerns over poachers being active in Simlipal again. The National Tiger Conservation Authority (NTCA) has also expressed concern over mass killings of elephants. Last year, about 10 elephants were killed in Simlipal.
