Authorities in Niger have arrested former Tuareg rebel leader Aghali Alambo for alleged arms smuggling and links to Al-Qaeda\'s North Africa wing. Alambo led Niger\'s last rebellion between 2007 and 2009. It ended after the mediation of Libya\'s late leader. Alambo was arrested after investigations that followed the June 2011 seizure in Niger of weapons and explosives smuggled out of Libya, Reuters quoted a police source as saying. Alambo will be questioned on charges of ties to criminal groups, financing terrorism and arms trafficking.
