DAKAR, Senegal — A wave of unrest in the West African nation of Guinea has left at least 11 people dead as protesters have poured into the streets nearly every day over several weeks to demand raises for teachers and the results of long-awaited municipal elections.

Thousands have turned out for demonstrations in Conakry, Guinea’s capital, and other major cities, and security forces have responded with tear gas and tanks. Violence has broken out at several rallies, and several journalists and news media outlets have been attacked.

The 11 victims include a police officer, Amnesty International said. Some people died of gunshot wounds, according to local news media reports, and the police officer was killed after being hit in the head with a rock.

Despite being a major exporter of iron ore, Guinea remains among the poorest nations in the world. It was one of a handful of West African countries hit in 2014 by the Ebola virus, which killed more than 2,500 people there. The economy has been crippled by poor governing and corruption.
