The Socio-Economic Rights and Advocacy Project on Monday lambasted Northern governors and monarchs over their call for the "censorship" of social media.
They had made the call at a meeting on insecurity in the region.
However, SERAP said in a tweet: "We condemn the call by the Nigerian Northern Governors’ Forum for a clampdown on social media.
This is both unconstitutional and antithetical to Nigeria’s international human rights obligations.
We’ll fight to hold these governors to account for their action."
