Climate activists in Austria attacked a famous painting by artist Gustav Klimt with a black, oily liquid, before one glued themselves to glass protecting the painting's frame.
Members of the group Last Generation Austria tweeted they had targeted the 1915 painting Death And Life at the Leopold Museum in Vienna to protest against their government's use of fossil energies.
After throwing the liquid on the painting, which was not damaged, one activist was pushed away by a museum guard while another glued his hand to the glass over the painting's frame.
