Authorities in Orissa have imposed prohibitory orders under Section 144 of the Indian Penal Code (IPC) in some parts of the riot-hit Kandhamal district on Monday to prevent a rally planned by tribals.

The Kui Samaja Kalyan Samittee had announced to hold a massive rally at Parampanga village. The rally was planned to protest alleged police atrocities against innocent tribals.

"We have clamped prohibitory orders in Daringbadi area and banned the rally as it may flare up tension in the region," a district police official said.

Kandhamal district had witnessed widespread communal violence following the murder of Swami Laxmanananda Saraswati at his ashram on Aug 23. The violence has claimed more than 40 lives and destroyed more than thousands of homes.
