ABUJA: Nigeria on Saturday hosts talks on Boko Haram with regional and Western powers, hoping for closer military cooperation and help with tackling the conflict’s dire humanitarian fall-out. The leaders of Benin, Cameroon, Chad and Niger are due to attend, with French President Francois Hollande, US Deputy Secretary of State Antony Blinken and Britain’s foreign minister Philip Hammond. Delegations from West African and Central African blocs, plus the European Union have also been invited. The summit comes as Nigeria’s military pushes deep into Boko Haram’s Sambisa Forest stronghold after recapturing swathes of territory in the northeast. The army has portrayed the Islamist militants as in disarray, but there have been warnings against any premature declaration of victory.
