BHUBANESWAR: Thousands of people, most of them Christians, have sought shelter in makeshift government camps in eastern India, driven from their homes by religious violence that has killed at least 13 people this week.

A district official said on Friday the religious clashes showed signs of abating in the state of Orissa, where Hindu mobs burnt more than a dozen churches and attacked Christians after a Hindu leader was killed.

"Hindu and Christian peace committees have been meeting and the leaders have appealed for calm," said Krishan Kumar, chief administrator of the worst affected Kandhamal district.

The bodies of two Christians believed to have been killed earlier this week had been found, Kumar told Reuters, taking the death toll from a week of violence to 13.

He said that a curfew imposed to halt the attacks would be lifted for a few hours.

At least 6,000 people were taking shelter in the government camps and about 5,000 were hiding in forests around Kandhamal, which has a history of communal and religious clashes, for fear of mob violence.

The numbers at the camps were expected to swell to 10,000 later on Friday, Kumar said. Most of India's billion-plus citizens are Hindu and about2.5 percent are Christians. In the Kandhamal area, more than 20percent of the 650,000 people are mainly tribal inhabitants who converted to Christianity.

Religious violence has troubled the tribal regions of Orissa for years, with Hindus and Christians fighting over conversions.

While Hindu groups accuse Christian priests of bribing poor tribes and low-caste Hindus to change their faith, the Christians say lower-caste Hindus convert willingly to escape a complex Hindu caste system.

On Friday, 37 Christians were reconverted to embrace Hinduism, although it was not clear whether they were intimidated into changing their faith.

"We have received such a report," Krishan Kumar, the district official said.
