A Guinean opposition official says there will be a march to protest the president's announcement that elections will be held on June 30.

Aboubacar Sylla, Guinean opposition spokesman, said Sunday that a peaceful demonstration will be held in the capital, Conakry, on April 18 to show objections to President Alpha Conde's decision to set the date of the elections, ignoring ongoing consultations over the polls' date.

The presidential decree was read Saturday evening on state television.

Guinea has not had a functioning parliament for four years, and it only held its first democratic presidential election in 2010. Disagreements over the electoral process already have caused violent protests.

Originally the vote was scheduled for May 12, but the opposition said it was pulling out because of concerns over election procedures.
