A senior government official who requested anonymity confirmed to AFP on Sunday that the Congolese intelligence agency ANR is holding Niarchos in Kinshasa.
The 33-year-old journalist, who writes for US magazines The Nation and The New Yorker, had made contact with armed groups including the Bakata Katanga militia, the official said.
“He made movements that were never previously reported to the authorities,” the official explained, noting that the government “must be vigilant” after the murder of two United Nations experts in 2017.
