Berlin, Ramadan 19, 1436, Jul 6, 2015, SPA -- A strong and united Europe is necessary to overcome challenges in member countries, German Finance Minister Wolfgang Schaeuble says. "We are able to solve issues better if Europe works together," Schaeuble tells reporters after meeting his Polish and French counterparts in Warsaw. According to dpa, he adds the meeting did not address the Greek referendum results, since finance ministers are waiting for Greece to put forward new proposals at Tuesday's eurozone summit in Brussels. --SPA 20:22 LOCAL TIME 17:22 GMT www.spa.gov.sa/w
