German prosecutors say the death toll from a crush at last weekend's Love Parade techno festival has risen to 21 after a young woman died from her injuries.

Duisburg prosecutors' spokesman Rolf Haferkamp said on Wednesday that the 25-year-old German woman died overnight in a hospital.
She was among those crushed at the festival in the western German city on Saturday.

More than 500 people also were injured in a stampede at a jammed tunnel that was the lone entrance to the festival grounds where thousands had gathered to party.
