A Nigerian journalist working for the privately-owned Daily Trust newspaper has been arrested in neighbouring Niger.
Lawan Adamu was investigating the story of migration of Africans to Europe through Niger’s town of Agadez when he was detained by local officials on Saturday, the paper’s editor, Mannir Dan Ali, told the BBC Hausa service.
“He was arrested on arrival at Agadez even before he started his work over allegations that he did not have valid documents to enter the area even though he obtained a visa from Niger’s consulate before he left Nigeria,” he added.
Mr Dan Ali said they are calling for his unconditional release.
Agadez, a gateway between west and north Africa, is being considered as a major transit point for thousands of African migrants who are transported across the Sahara Desert to Libya for onward journey to Europe through the Mediterranean.
