Guinea's government spokesman says that following President Alpha's Conde's election victory, officials are preparing for possible violence because the runner-up has vowed to protest the results.

Albert Damantang Camara said Sunday that the government is "worried" because "there have never been peaceful demonstrations" in the West African nation.

The election commission announced Saturday night that President Alpha Conde won a second five-year term with nearly 58 percent of the vote and defeated his closest challenger Cellou Dalein Diallo by a large enough margin to avoid a runoff.

Diallo has alleged fraud and said he would call for demonstrations, though he has not specified when.

At least three people were killed in clashes in the weeks before the vote, and Guinea's elections have also been marred by violence.
