The United Nations Security Council on Thursday implemented its first individual sanctions against three Malians linked to armed groups and accused of violating a 2015 peace agreement, according to diplomatic sources.The council slapped travel bans on Mohamed Ousmane Ag Mohamedoune, secretary general of the Coalition for the People of Azawad, Ahmoudou Ag Asriw of the Imghad Tuareg Self-Defense Group and Allies, and Mahmadou Ag Rhissam, a businessman and member the High Council for Unity of Azawad, the sources said.It marks the first time the UN has targeted individuals since the 2017 adoption of a general sanctions regime against Mali."The sanctions target intermediate officials responsible for blocking the implementation of the peace agreement, particularly because they have links with terrorist groups or drug trafficking activities," explained one diplomat, who asked to remain anonymous.The sanctions could be expanded to freezing of assets, he added, noting the three concerned regularly move between different countries in the Sahel. * Sign up to News24's top Africa news in your inbox: SUBSCRIBE TO THE HELLO AFRICA NEWSLETTERFOLLOW News24 Africa on Twitter and Facebook.
