Hundreds of Tamil prisoners in Sri Lanka, many of whom have spent nearly two decades in jail without seeing the inside of a courtroom, have initiated a hunger strike to demand their immediate release. A total of 223 prisoners have joined the strike at jails across four different cities, the BBC reports. Many have been imprisoned under terrorism laws for alleged links to the Liberation Tigers of Tamil Eelam — a rebel group that waged a 26-year civil war against the Sri Lankan government until its defeat in 2009. The laws allow Lankan authorities to detain an individual on suspicion of being a terrorist for up to 18 months without trial, although many of the inmates were incarcerated as far back as 1997.
