Nigerien opposition leader and former prime minister Hama Amadou was jailed on Monday after being held for questioning for three days over his alleged role in post-election violence, prosecutors told AFP. Amadou faces "many charges" including "complicity" in demonstrations and property damage, prosecutors said, after wide protests over the results of a presidential election that handed victory to ruling-party candidate Mohamed Bazoum over the opposition's Mahamane Ousmane. bh-stb/tgb/ach
