Conakry - Police shot dead a teenage protester on Monday as an anti-government demonstration flared into violence, according to medical sources and relatives.
The 19-year-old was hit by a "bullet to the neck fired by a police officer" in the west African nation's capital Conakry, his father Mamadou Dian Barry told AFP.
Abdoulaye Barry, the director of a clinic treating several wounded said: "The body is in my ambulance. I'll drop it off at the morgue. Since the morning, I have been driving around violent areas of the city to evacuate casualties among civilians and security forces."
The scale of the protest wasn't immediately clear but witnesses said violence erupted as demonstrators took to the streets as part of a day of protest over alleged fraud in September's parliamentary polls.
"At least 17 civilians were wounded, including four by gunshots. They have been sent to three hospitals," Alimou Souare, a doctor treating some of the protesters, told AFP.
He said other protesters had suffered broken ribs or had been kicked and beaten with batons.
"A policeman fired from point blank range at my nephew," trader Mamadou Lamarana Lah said as he fought back tears.
Two policemen were also injured in the clashes, according to Ibrahima Balde, the head of the National Gendarmerie.
The violence follows a 15 November ruling by the Supreme Court confirming the election results handing power to President Alpha Conde's party.
Conde's Rally of the Guinean People (RPG) and its allies won an absolute majority of 58 seats in the 114-member parliament. But the 28 September polls have come under heavy criticism from opposition parties, which won a total of 53 seats.
The opposition coalition alleged "massive fraud", accusing the government of "robbery" and claiming the polls were marred by irregularities including ballot stuffing, voter intimidation and minors casting votes.
International observers also said serious flaws had affected the credibility of the vote.
