German leaders observe a minute of silence during a ceremony at the Bernauer Strasse memorial GALLO/GETTY

The events began overnight on Saturday at a chapel, with a seven-hour-long reading about the lives of those killed while seeking freedom as they fled East Germany for West Germany. At a sombre ceremony in Berlin, Mayor Klaus Wowereit, Chancellor Angela Merkel and President Christian Wulff paid tribute to the 136 people killed trying to get over the Wall.

Church bells peeled while trains and traffic came to a standstill at noon across Berlin for a moment of silence for the victims.
