Elite police commandos patrolled a suburb of the Sri Lankan capital Friday after hundreds of rampaging Buddhist hardliners torched a Muslim-owned business in the latest in a series of mob attacks.
At least three people were wounded when majority Sinhalese mobs stoned and later set fire to a clothing store in Pepiliyana on Thursday night, police spokesman Buddhika Siriwardena said.
"We have deployed extra units of STR (Special Task Force commandos) and police to guard the area," Siriwardena told AFP. "The situation was brought under control within a few hours."
No arrests had been made, Siriwardena said.
The authorities have not declared a motive for the attack, but official sources said it appeared to be a part of the ongoing targeting of minority Muslim businesses by a group of Sinhala-Buddhist hardliners.
Hundreds of men stormed the Fashion Bug store, smashed several vehicles parked outside and set fire to merchandise before escaping on Thursday night, witnesses told AFP.
Army units were called in disperse the mob as tension gripped the area.
The latest attack came a day after Sri Lankan police set up a hotline to tackle complaints about anyone suspected of "inciting religious or racial hatred".
Mobs pelted stones at another Muslim-owned clothing chain near Colombo in January while Muslim businessmen have also complained of random stone-throwing incidents and intimidation.
Buddhist hardliners last month forced Islamic clerics to withdraw "halal" certification from food sold in the local market, saying it was offensive to the majority non-Muslim population.
President Mahinda Rajapakse, who is a Buddhist, urged monks earlier this year not to incite religious hatred and violence.
The United Nations estimates that Sri Lanka's ethnic civil war claimed at least 100,000 lives between 1972 and 2009, when Tamil rebels were crushed in a major military offensive.
Less than 10 percent of Sri Lanka's population of 20 million are Muslim. The majority are Sinhalese Buddhist, while most Tamils are Hindu.
