The Chadian peacekeepers opened fire on a crowd demonstrating against their presence in Bangui on Monday, killing one person and injuring several others, protesters said.
An officer with the African Union Peacekeeping Mission (MISCA) confirmed that Chadian peacekeepers had clashed with demonstrators near the airport at Bangui, but could not confirm the death or provide further details.
The clash was the latest sign of rising tensions between the majority Christian population in Bangui and the Chadian forces, complicating international efforts to calm inter-religious violence in the African state.
The locals had accused the Chadian troops of siding with Muslim Seleka rebels, who seized power in Central African Republic in March, unleashing a wave of looting and killings, adding that many of the Seleka rebels came from Chad.
The spokesman for the international medical charity Medecins Sans Frontieres (MSF) said that around 40 people had been treated for injuries at their airport medical centre, most of them lightly hurt in a panicked stampede.
MSF spokesman Martin Searle said that one person had received treatment for a minor gunshot wound, while three others were seriously injured after being hit by a vehicle.
The protesters said that the Chadians drove their vehicle at the crowd after demonstrators threw stones at them, chanting “No Chadians in Bangui!”
