The authorities on Monday imposed a curfew and arrested more than 20 people in Kandy for the violence that ensued after the death of a Buddhist in Teldeniya, who was killed when he clashed with four Muslims.
The decision has been taken in a cabinet meeting with the view of preventing the riots from spreading to other parts of the country. "The curfew was imposed to control the situation in the area", said police spokesman Ruwan Gunasekera.
"It was chose to take stern action against people who are instigating violence through Facebook, the spokesman, Dayasiri Jayasekara, said". "We are urging our people to remain calm, but when their houses and livelihoods go up in flames, how long will they bear it?"
Sri Lanka's government condemned recent arson attacks and riots in the central district of Kandy - which damaged some places of worship, residences and businesses. The country was under a state of emergency for almost three decades when the government fought Tamil rebels in the civil war that ended in 2009.
A police official said 24 people had been arrested over the killing so far.
Prime Minister Ranil Wickremesinghe also ordered an investigation into alleged police inaction in handling the clash.
Sinhalese Buddhists make up for 70 per cent of Sri Lanka's population of 21 million while Muslims comprise of 9 per cent. Another 13% of the population are Hindus. Similar violence occurred last month when mobs set fire to Muslim-owned businesses and a mosque.
