Violence broke out late Monday, three weeks after terrorist bombings killed 258 people, with rampaging mobs carrying out arson attacks and 2,000 people vandalizing a mosque, witnesses said, AFP reported.
Police announced another nationwide curfew for a second night to try and stop the violence.
The curfew had been in place all day in North-Western Province (NWP), where police said a 45-year-old Muslim man was slaughtered in his carpentry shop late Monday by a crowd carrying swords.
Fauzul Ameen was buried Tuesday at a Muslim cemetery in Nattandiya under tight security. Heavily armed troops and police backed by armored personnel carriers guarded a service attended by around 100 people.
Police said Tuesday that 13 people had been arrested including Amith Weerasinghe, a man from Sri Lanka's majority Buddhist Sinhalese community on bail for his role in similar riots in March last year.
Elsewhere in NWP, north of Colombo, attackers outnumbering police and security forces set fire to Muslim-owned shops, vandalized homes and smashed windows, furniture and fittings inside several mosques.
In the adjoining Gampaha District, men on motorbikes led arson attacks in the town of Minuwangoda, 45 kilometers (30 miles) north of Colombo, local residents told AFP.
An owner of an electronic goods store said police and security forces appeared to be overwhelmed and that by the time troops fired in the air to disperse the mobs it was too late.
In the NWP, attackers have systematically targeted mosques for two days, local clerics told AFP. In the town of Kinyama, two mosques were smashed as outnumbered armed police and troops stood by.
"Security forces are assisting police who have been ordered to use maximum force to contain the violence," police spokesman Ruwan Gunasekera said.
Political commentator Victor Ivan suggested that the violence was politically orchestrated.
"The opposition feels that they can gain when there is instability and the government appears to be weak," Ivan told AFP. "There is evidence of junior level opposition figures instigating communal violence."
He said the political establishment, including the opposition, had failed to provide leadership and restore confidence after the April 21 attacks claimed by the Daesh terrorist group.
In an address to the nation on Monday night, Prime Minister Ranil Wickremesinghe said the unrest would hinder investigations into the attacks that targeted three churches and three luxury hotels.
In a separate TV address, Police Chief Chandana Wickramaratne warned of stern action against rioters, and said that constables have been issued orders to use maximum force.
The attacks came during the Muslim holy fasting month of Ramadan. Muslims make up around 10 percent of Buddhist-majority Sri Lanka's population, and Christians about 7.6 percent.
A state of emergency has been in place since the bombings and security forces have been given sweeping powers to detain suspects.
Internet service providers said the telecoms regulator on Tuesday extended a social media ban to Twitter. Earlier, Facebook, WhatsApp, YouTube and Instagram had been blocked to prevent the spread of messages inciting violence.
