Singh said that as the state government has "failed" to control the rampant poaching in the UNESCO World Heritage Site, the Centre should immediately intervene to halt the menace.
"If the state government does not act, the Centre must intervene immediately," Singh told reporters here.
"Assam is known worldwide for the one-horned rhino and its tea. The rhinos are being poached in Kaziranga and the state government is a mute spectator to it," he said.
Rhino horns are highly valued in the international black market fetching lakhs of rupees for their so-called medicinal values and for being a status symbol for a section of people in south east Asian countries.
