The lawyer for Cameroon’s arrested main opposition leader says he now faces eight charges including sedition, insurrection and inciting violence.

Christopher Ndong told The Associated Press Thursday that Maurice Kamto also faces charges that include hostility against the fatherland and disruption of peace. If he is found guilty, he could face five years to life in prison.

Kamto and members of his Movement for the Renaissance of Cameroon party were arrested on Monday in Douala. The party over the weekend had called for protests against what it called irregularities in the Oct. 7 election that saw President Paul Biya easily win a seventh term. Official results said Kamto finished a distant second.

More than 100 protesters were arrested in various cities. International rights groups have called for their release.
