COLOMBO, Sri Lanka (AP) — Three inmates were killed and more than 20 were injured in two separate prison clashes in Sri Lanka on Thursday and Friday, a government minister said. Two inmates died Friday morning at Kuruwita Prison in Kuruwita town about 80 kilometers (50 miles) from the capital, Wijepala said. Prison officials could not immediately be reached for comment. Separately, prison officials used tear gas to control inmate protests at the Pallansena Correctional Center on Friday. “The number of prisoners in Sri Lanka today is four times the capacity,” said Senaka Perera, president of the Committee for Rights of Prisoners.
