Opposition leader in Niger and former prime minister Hama Amadou has been jailed after being held for questioning for three days over his alleged role in post-election violence. Amadou faces many charges including complicity in demonstrations and property damage, after widespread protests over the results of a presidential election that handed victory to ruling-party candidate Mohamed Bazoum over the opposition's Mahamane Ousmane. Amadou, who finished runner-up in the 2016 election, was barred from contesting the election this time because of a criminal conviction.
