Nigerian television and radio stations should not use Twitter to gather information and have to de-activate their accounts, the broadcast authority said following the move to suspend the US social media giant in Africa's most populous country.

Nigeria's government suspended Twitter's activities on Friday, two days after the platform removed a tweet by President Muhammadu Buhari that threatened to punish secessionists. Nigerian telecoms firms have since blocked access to Twitter. Buhari has previously been accused of cracking down on freedom of expression, though his government has denied such accusations.
International diplomats responded with a joint statement in support of "free expression and access to information as a pillar of democracy in Nigeria."
Twitter has called its suspension "deeply concerning" and said it would work to restore access for all those in Nigeria who rely on the platform to communicate and connect with the world.
The National Broadcasting Commission, in a statement dated June 6, told broadcasters to "suspend the patronage of Twitter immediately."
