A rhino was killed on Sunday and its horn removed by suspected poachers at the Kaziranga National Park, forest officials said.
The full-grown female rhino was found dead at the Borbhog camp in the Burapahar range in the afternoon. Empty cartridges of AK-47 and .303 rifles, along with double barrel gun ammunition, were found at the spot.
This is the third incident of a rhino being killed in the Burapahar range within the last one and a half months.
A massive combing operation has been launched in the area to nab the poachers, sources said.
Altogether 25 rhinos have been killed by poachers in the national park this year while 70 rhinos have died, which include 23 deaths in flood and the rest due to natural causes.
