Guinea's opposition sought to spur protests across the country against a disputed election timetable on Thursday after days of violent clashes in the capital, even as the president ruled out any review, France 24 radio reported.

Violence between supporters of the opposition Union of Republican Forces (UFR) and police during unauthorized protests in Conakry left several dead in recent days, but supporters are undeterred and seeking to consolidate their regional backing.

Guinean President Alpha Conde insisted on Wednesday that the country's constitution rules out the kind of changes to the election timetable sought by opposition supporters.

"The Guinean constitution requires that presidential elections take place on a precise date," Conde told reporters after a meeting with French President Francois Hollande in Paris. "We will do everything possible to maintain order in the republic."
