The Berlin Wall comes down

The Berlin Wall fell 25 years ago on Sunday, a key event in the collapse of communism and the preface to Germany's reunification in 1990.

The anniversary is being celebrated in Berlin with concerts, speeches and the release in the evening of thousands of balloons illuminating a 15-kilometer (nine-mile) stretch of the former Cold War barrier.

At least 138 people, including several children, lost their lives along the Cold War barrier, according to the latest research by the Berlin Wall Foundation.
