Villagers in southern Senegal clashed with gendarmes during protests Saturday over the lack of running water, the local gendarmerie and the media reported.
During the clashes, which took place at Cap Skirring in the Casamance region, the gendarmes used tear gas to disperse the crowd, their spokesman said.
According to media reports citing witnesses, the gendarmes fired live rounds at the protesters, wounding some of them.
The villagers ignored a ban on the demonstration issued a day earlier, which led the gendarmes to intervene, their spokesman said.
The demonstrators threw stones at them and set tyres on fire.
Officers arrested 16 people including four suspected organisers of the protest, the spokesman added.
