Police have poured into a village near Sri Lanka's capital for the funeral of a teenager shot dead by troops during a protest against contaminated water.
Security in Weliweriya village was strengthened as a hospital official said a third person had died after succumbing to injuries sustained during the army's crackdown on the residents' protest on Thursday.
"We have another three people in the intensive care and their condition is serious," spokeswoman for the hospital in Colombo, Pushpa Soysa, said.
Police said 17-year-old Akila Dinesh Jayawardena was killed when troops fired at unarmed residents demonstrating against a factory which they accused of discharging chemical waste and polluting ground water.
Jayawardena was buried on Sunday evening amid tight security by police commandos who were seen near the village cemetery too.
Mourners returning from the burial stopped briefly at the village centre to shout slogans denouncing the authorities and pressing their demand for safe drinking water. They dispersed peacefully, witnesses said.
Roman Catholic priest Lakpriya Nonis said armed troops stormed his St Anthony's church shortly after Thursday's protest and assaulted men, women and children who had sought refuge there.
"They came into the church premises and assaulted people sheltering inside," the priest told reporters after Sunday's burial.
Official sources said nearly 50 people were injured with most of them suffering bullet wounds, while some had been beaten with sticks and rifle butts.
The privately-run Sunday Times said up to six people had been killed and that authorities were not revealing the total number of casualties.
The burials of the other two victims are yet to be decided.
Dipped Products Ltd says it's not responsible for the pollution at Weliweriya.
Its factory remains shut because of the protest.
