Nigeria wants to censor Yellow Sun
Nigerian censors say parts of the movie Half of a Yellow Sun could undermine national security.
They want cuts to allow the film - which stars Chiwetel Ejiofor and Thandie Newton and is partly set during Nigeria's 1960s civil war - to be shown in its home country.
A statement said the board has not received a response from the exhibitors to a May 27 letter "requiring the distributor to expunge/edit some clearly stated objectionable aspects."
There was no immediate response from the British-Nigerian producers of the movie which made its debut in Britain in April and in the United States in May.
It comes as Nigeria is threatened by an Islamic uprising in the northeast, jeopardising unity between the mainly Muslim north and predominantly Christian south.
The film is based on an award-winning novel by Chimamanda Ngozi Adichie.
