Niger on Friday jailed two journalists who were part of a trio detained in early May for plotting against state authority, their employer told AFP.

Reporters have regularly been detained since a junta seized power in a 2023 coup, a practice denounced by free speech activists across the world.

The three journalists worked for the Sahara FM private radio and were arrested in the central city of Agadez.

They had reported that security contracts between the west African country and Russia -- a key junta ally -- had ended. "A military court judge remanded the two men to Kollo prison," Sahara FM owner Air Info said on Friday, referring to a jail some 50 kilometres south of the capital Niamey.
