Bangladesh is deploying thousands of extra police to Rohingya refugee camps in the south, officials said, after several mostly unexplained killings have sown fear among hundreds of thousands of people who have fled from neighboring Myanmar.
Since August, when a military crackdown in Myanmar forced many of the Muslim minority to cross the border into Bangladesh and seek shelter in the crowded camps, 19 people, some of them community leaders, have been killed.
Police have made a number of arrests in connection with some of the killings, but say the motives often remain unclear.
