Two people were killed and seven others wounded when gunfire erupted overnight in areas of Guinea's capital Conakry amid reports of looting, medics and residents said Tuesday.
"We had two dead and seven injured from bullet wounds," said a doctor at a Conakry clinic, a figure that was confirmed by the victims' families.
Residents said violence broke out when "men in uniform along with civilians" started looting in neighbourhoods of Conakry where a majority of ethnic Peuls live.
It was not immediately clear if the latest violence was linked to the political protests by the opposition over the past week that have led to at least eight people killed and more than 200 injured.
The opposition has been calling for transparency during the planned May 12 legislative polls.
Guinea's political factions often divide along ethnic lines, particularly between the Peuls and the Malinkes.
The main opposition party, the Union of Guinea Democratic Forces, is led by a Peul, Cellou Dalein Diallo, who was defeated in the 2010 presidential vote by President Alpha Conde, a Malinke.
Opposition figures met with Conde on Monday to try to resolve the conflict but later said they were disappointed with the encounter.
The vote in the troubled West African country was due to have taken place in 2011, but has been postponed several times. As the elections now close in, the opposition have ramped up demonstrations to demand a free and transparent vote.
On February 23, the leading opposition parties in Guinea said they were pulling out of the election, accusing the ruling party and the electoral body of turning the vote into a farce
