Mali’s government has denied allegations that a French air strike on Sunday killed guests attending a wedding.
The country’s defence ministry said a joint operation with French forces had killed only Islamist militants.
The French military have also denied causing civilian casualties, though witnesses said up to 20 wedding guests were killed.
The medical charity, Medecins Sans Frontieres, said armed men targetted an ambulance which was transferring several of the victims to hospital on Tuesday.
It said one of them – a man in his sixties – had died after being tied up and assaulted.
