More than 50 opposition activists have been arrested in Cameroon, including opposition party leader Maurice Kamto, who was arrested on Saturday for participating in an unlicensed demonstration, the opposition spokesman said, reports AFP.
"There have been widespread arrests of activists” wrote former presidential candidate Olivier Nissak on his Facebook page.
Kamto took second place in the presidential election with 14.23 percent of the vote behind Paul Biya, who was re-elected for a second term after winning 71.28 percent of the vote.
Ndoki, one of Kamto's lawyers, told the Constitutional Council to denounce "massive and systematic fraud".
An unsigned publication was circulated via social networking sites calling for "national resistance to the electoral segregation" by participating in the demonstration on Saturday in Douala.
Activists from the party "for the renaissance of Cameroon" were arrested during the demonstration.
A Cameroonian journalist was also arrested during the demonstration as he was covering media coverage of the operation, according to sources close to AFP.
"The detainees are being held at the judicial police station in the Punango district of Douala," former presidential campaign leader Paul Eric King told AFP.
On Monday, the Constitutional Council announced the results of the presidential election with the victory of Paul Biya, 85, who has been in power for 36 years.
