Niger’s coup leaders have given the French ambassador 48 hours to leave the country as bilateral ties continue to deteriorate rapidly.
The junta said Sylvain Itte had refused to respond to an invitation to meet Niger’s foreign minister.
France, a former colonial power, said the “putschists have no authority” to order such an expulsion.
Paris opposes July’s coup, saying that ousted President Mohammed Bazoum must be returned to office.
Friday’s announcement was made by Niger’s foreign minister installed by the junta.
