Press Freedom clash

Journalists protesting against the death of a Cameroonian newspaper editor have clashed with riot police in the capital Yaounde.



Cameroon Express editor Bibi Ngota died last month in a Yaounde prison.



He was one of three journalists detained in March on charges of fraud and using false documents.



His family has rejected the government\'s explanation that he died of an HIV-related infection.



Meanwhile, the journalists protesting his death were prevented from staging a sit-in at the prime minister\'s office to mark World Press Freedom Day.



The authorities say the protesters had not given them proper notice to hold a public rally.



Newspapers in Cameroon are subject to considerable official restrictions and tough libel legislation is in place.
