[Theresa Mallinson] A decade ago Eritrean President Isaias Afewerki shut down his country's independent press, and arrested 21 journalists and politicians. He's detained many more of his citizens without trial since then. With no free media left to report on their fate, news of the prisoners has been hard to come by, but the ten-year anniversary of their disappearance has brought renewed calls by international NGOs for their release.
