Installation featuring countless red threads opens at Austrian ex-Nazi death camp

Red ropes and larger-than-life dresses float in the tunnel of a former Nazi death camp in Ebensee, Austria, as the exhibition by Japanese artist Chiharu Shiota "Where are we now?" opens to the public.

More than 8,000 prisoners died at the Ebensee camp between 1943 and 1945, mostly of hunger and malnutrition as they were forced to work on the construction of a huge tunnel network.

Opening her exhibition at the site, Shiota says the theme of her work is "absence in the existence".
