Police and riot squads have been deployed after three inmates were killed and nearly two dozen others were injured in separate prison riots across Sri Lanka. Two more prisoners were killed on Friday morning during a second riot at Kuruwita prison, about 80km (50 miles) from the capital, he said. Between the two incidents, 23 inmates were injured and admitted to hospitals, Wijepala said, adding that police and special forces ‌brought both riots under control. Wijepala told parliament the violence was related to narcotics dealers and rival criminal gangs. “The number of prisoners in Sri Lanka today is four times the capacity,” said Senaka Perera, president of the Committee for Rights of Prisoners.
