Nigeria has lifted its ban on Twitter â€“ seven months after clamping down on the social networking site.
Nigeriaâ€™s government suspended Twitter last June after the company deleted a tweet by President Muhammadu Buhari about punishing regional secessionists.
Authorities accused the social media firm of siding with the secessionists.
But the government said it was reversing the ban after Twitter agreed to conditions including opening a local office in Nigeria.
The move allows millions of people in Africaâ€™s most populous nation to use the platform again.
Some users had continued to access the site after the suspension using virtual private networks (VPNs), but the government vowed to clamp down on those still tweeting â€“ including media organisations.
The move last year by Nigeriaâ€™s government sparked international outcry over freedom of speech.
The social media companyâ€™s decision to register itself in the country showed it was committed to Nigeria, the countryâ€™s information technology development agency said.
Twitter has not yet commented on Nigeriaâ€™s decision to lift the ban.
The government had ordered internet providers to block Twitter, alleging it was being used to undermine â€œNigeriaâ€™s corporate existenceâ€ through the spreading of fake news that could potentially have â€œviolent consequencesâ€.
It came after Twitter removed President Buhariâ€™s post referring to the 1967-70 Nigerian Civil War and to treating â€œthose misbehaving todayâ€ in â€œthe language they will understandâ€.
Twitter is popular with many Nigerians, and the platform has been used as a mobilising tool. Activists used it to rally support during protests against police brutality under the hashtag #EndSars, which gained global attention.
