YANGON (Reuters) - Two Reuters journalists, Wa Lone and Kyaw Soe Oo, have been detained in Myanmar since Dec. 12, 2017. At the time of their arrests, they had been working on an investigation into the killing of 10 Rohingya Muslim men and boys in a village in Rakhine state.
After six months of pre-trial hearings, a court is set to decide on Monday whether or not to charge the reporters under the Official Secrets Act, which carries a maximum penalty of 14 years in prison.
