Berlin, Muharram 16, 1436, Nov 9, 2014, SPA -- Tensions over Moscow's intervention in eastern Ukraine cast a shadow over Sunday's celebrations in Germany marking the 25th anniversary of the fall of the Berlin Wall, with the last leader of the Soviet Union Mikhail Gorbachev calling on Europe and Russia to reopen dialogue, dpa reported. "Now is not the time for recriminations. Let us work hard to restore confidence," Gorbachev, 83, told a symposium in Berlin just 24 hours after he warned that a new Cold War was taking shape. His call came in the wake of warnings from Germany and other European Union states that further sanctions might be imposed on Moscow if the conflict between Kiev and pro-Russian separatists intensified. Speaking at a ceremony on Sunday at the Berlin Wall Memorial Chancellor Angela Merkel said the breaching of the Cold War barrier on November 9, 1989 was a sign of hope for the series of crises currently facing the world. -- SPA 19:25 LOCAL TIME 16:25 GMT www.spa.gov.sa/1293105
