Germany's capital has come alive to the sound of techno music as the famous Love Parade returns to Berlin for another year

Hundreds of thousands of people have descended on Tiergarten park for the 15th annual festival. DJs including Pete Tong, Felix da Housecat, Paul van Dyk and the festival's founder Dr Motte are among 250 playing on 50 carnival floats. There had been fears that the festival might be cancelled after last year's event made a financial loss. But corporate sponsorship and a deal with the Berlin Convention Centre to provide beer and sausages saved it. From humble beginnings as a small street party of 200 people in a divided Germany in 1989, the festival expanded rapidly. Numbers have dropped, with some saying it has become too commercialised. Organisers say the parade has stuck to its alternative, sub-cultural roots.
