In Thummadora, another affected town about 40km east of Colombo, Abdul Wahid Mohamed Risvi, a 44-year-old father of three, is terrified about the possibility of more violence.
"I haven't gone to work in a week because I cannot leave my children alone. Many Muslims also said they no longer trust the police or the military to protect them.
The only vehicle which could take 49-year old Saleem Ameer to the hospital was engulfed in flames.
Meanwhile, residents in the affected towns report their long-existing relationships with their neighbours have deteriorated.
"We maintained a good relationship with the Sinhala community before the incident.
Since the end of the war, tensions have increased between the majority Sinhala community, which constitute 75 percent of Sri Lanka's population, and Muslims, who at 9.7 percent consider themselves to be a distinct ethnic group in the country.
Last year, Muslim mosques and business were burned in an arson attack carried out by Buddhist mobs.
A month earlier, such a nightmarish scenario would have hardly seemed imaginable in Sri Lanka's northwest province, which had been largely unaffected by the sporadic ethnic violence seen in other parts of the country in the decade since Sri Lanka's civil war ended.
