Curfew was clamped in four major towns of Orissa's Kandhamala district on Tuesday after one person was killed and at least 24 others injured during a VHP-sponsored bandh. The meeting was called to protest the alleged attack on an anti-conversion leader. 

"Following large-scale violence, we have imposed curfew in the district headquarters town of Phulbani, Baliguda, Daringibadi and Brahmanigaon to prevent further flare up", said Revenue Divisional Commissioner (southern division) Satyabrata Sahu.

Expressing concern over the violence on Christmas day, Chief Minister Naveen Patnaik appealed to the people to maintain peace and communal harmony.

A youth was killed in mob violence at Barakhamba, a senior police officer said, adding that he was yet to be identified. The details of the incident are not known yet.

"The situation is tense but under control. We are keeping a close watch," the official said.
