Sri Lanka deployed hundreds of troops and elite commandos on Sunday to contain riots at an overcrowded prison in which one inmate was killed and six others wounded, police said. Deputy police inspector-general Sanjeewa Medawatte said the situation was under control after inmates destroyed multiple buildings on Saturday inside Mahara Prison, just outside the capital Colombo. The latest unrest came almost a month after another prison riot in the same region, in which 10 guards and 21 inmates were killed. Medawatte said inmates at Mahara Prison had completely destroyed the kitchen, the hospital, a newly built rehabilitation building and vocational training facilities. More than three-quarters of the inmates in Sri Lanka are remand prisoners awaiting trial, and most are held in connection with drug offences.
