Opposition supporters in Guinea staged protests and erected barricades in the mining towns of Boke and Kamsar on Tuesday, disrupting some shipments of the aluminium ore bauxite, according to mining sector officials.
Police responded with teargas and clubs, a local resident said.
The West African nation’s opposition parties are calling for the publication of results from recent local elections, which allies of President Alpha Conde say they have won.
Violent protests erupted in the capital Conakry several days ago.
“It’s a situation that is causing losses with our boats stranded and waiting to be loaded,” Frederic Bouzigues, managing director of Société Minière de Boke (SMB), told Reuters.
Boke and Kamsar were scene of repeated bouts of unrest last years with local residents protesting about electricity cuts, pollution and a perceived failure of mining projects to raise living standards.
“It’s really hot here at the moment with these barricades and tyres being burned by the protesters. The gendarmes intervened with teargas and clubs,” said Boke resident Mamadou Diallo.
