(Compass) – Two Christian health workers in Bangladesh were hacked to death on July 29. Police and local officials believe Islamic extremists likely were responsible for the murders. The incident took place about 150 kilometers from the capital, Dhaka . Tapan Kumar Roy, 30, and Liplal Marandi, 35, worked for Christian Life Bangladesh (CLB). Along with educational films on arsenic poisoning, mother-and-child health care and AIDS prevention, they often showed the Jesus Film at the invitation of local villagers. A well-known Christian leader familiar with the two evangelists said an official at a local madrassa (Islamic school) had threatened the men verbally prior to the murders. Some villagers had also threatened to kill Roy and Marandi if they continued to show the Jesus Film. Police arrested a man named Monir Hossain in connection with the murders, which they are still investigating. Bangladesh is facing an overall deterioration in human rights, both for the Muslims who form 83 percent of the population and for religious minorities.
