Germany is celebrating the anniversary of its reunification 21 years ago after four decades of Cold War division.
Chancellor Angela Merkel and President Christian Wulff are attending the main ceremony marking Monday's anniversary in Bonn, the former German capital.
West Germany and communist East Germany were united on Oct. 3, 1990, less than 11 months after the east opened the Berlin Wall.
Merkel _ who grew up in East Germany _ said ahead of the anniversary that "some serious differences" remain, notably in that unemployment remains higher in the east.
But she said in her weekly video podcast that "we are on the right track." She added that "we can look back with great pride on reunification."
