UN chief says the 'slaughter' in Syria must stop

UN General-Secretary Ban Ki-moon said Wednesday the world must unite in its response to Syria's civil war and do all it can to stop what he called the slaughter taking place there.

Speaking in Sarajevo, Ban said other countries intervened in Libya and the Ivory Coast to stop widespread killing there, but failed during Bosnia's 1992-95 war to prevent Bosnian Serbs from killing more than 8,000 Muslim Bosniaks in Srebrenica while the town was officially under UN protection. (AP)
