Police in Cameroon arrested 19 supporters of opposition leader Maurice Kamto, who disputes the results of October presidential elections, at protests against President Paul Biya on Sunday, local authorities and witnesses told AFP.

The arrests happened at two different places in the town of Bafoussam in the country's west where Kamto backers were picketing, they said. Kamto, who according to official results came second with 14 per cent of the vote behind incumbent Biya with seven percent, called Friday for an independent vote recount.
