An Angolan teenager, who was arrested about two months ago after printing T-shirts calling President Jose Eduardo dos Santos a dictator, has gone on hunger strike, his lawyer says.
Manuel Chivonde Nito Alves's lawyer said he was protesting against his unjust and inhumane treatment.
Mr Alves had the T-shirts printed for an anti-government march, which was dispersed by the police in September.
He has been charged with insulting the president.
Mr dos Santos has governed oil-rich Angola since 1979.
In the past two years, there have been a number of demonstrations against the government.
Despite its growing economy and the huge wealth of a tiny elite, most Angolans live on about $2 (£1.25) a day.
