CONAKRY, Guinea, Dhu-AlQa'dah 1, 1436, Aug 16, 2015, SPA -- Riot police in Guinea used tear gas to break up a rally on Saturday demanding the return of a former military ruler who wants to run for president despite facing charges related to a 2009 massacre. An Associated Press reporter at the scene saw riot police fire tear gas canisters around 7 p.m. when about 200 supporters of Moussa "Dadis" Camara who had gathered at the airport in Conakry refused to disperse. -- SPA 00:55 LOCAL TIME 21:55 GMT www.spa.gov.sa/w
