RFA A court in Cambodia has added new anti-government conspiracy charges against three environmental activists who already are serving jail terms of up to 20 months for incitement convictions, in a move that could keep them in prison for 10 years, their lawyer said Wednesday. The Phnom Penh Municipal Court added the charges against Mother Nature Cambodia activists Long Kunthea, Phuon Keoraksmey, and Thun Ratha on Monday after investigation judge Im Vannak covertly brought each of them into the court for questioning without the presence of an attorney, said their lawyer Sam Chamroeun. The trio now faces an additional sentence of at least 10 years each if convicted on the conspiracy charge.
