Kuki-Zo civil society organisations have "warned" the Meitei community against climbing the Thangjing Hill in Manipur's Churachandpur district.
The Thangjing Hill is considered a sacred site for Meiteis who visit it in April.
Since the ancient times, the Meiteis have been going on an annual pilgrimage to the hilltop shrine of Ibudhou Thangjing, the guardian of the mountains.
The Kuki-Zo tribes deny the hill is exclusively a sacred site of the Meiteis.
