Two youths were shot dead and several others left wounded in clashes between Guinean police and protesters at a funeral march for those killed in recent anti-government demonstrations, the authorities and the family of one of the victims said.
The unrest started as hundreds marched in the capital Conakry carrying coffins of people killed in unrest since mid-October that has shaken the poor West African country.
Demonstrators have taken to the streets over suspicions that President Alpha Conde is seeking to prolong his rule.
According to an opposition toll, around 15 protesters have been killed during the weeks of bloody clashes with security forces, with dozens injured. The government has said one police officer was killed, but have not given an updated number of casualties.
