On Friday, members of Italian activist group Ultima Generazione threw bags of flour over a car painted by Andy Warhol, currently being exhibited in Milan, as part of their campaign of civil disobedience highlighting the need to address the climate crisis.
Two members of the group then glued themselves to the car at the Fabbrica del Vapore complex, while others burst paint-filled balloons over the floor and glued themselves to it.
The show at which the protest was staged is displaying a BMW car painted by the master of Pop Art, which was featured in the 24 Hours of Le Mans race.
Ultima Generazione have staged a series of controversial protests in recent months in hopes of alerting the public and government officials to looming environmental collapse.
These stunts have included blocking rush-hour traffic in big cities, disrupting people taking private flights, spraying paint over the offices of institutions linked to fossil fuels, and protests similar to Friday's, involving important works of art.
Ultima Generazione is demanding the immediate halting of the reopening of decommission coal plants, and the scrapping of new gas-drilling projects in Italy.
The group also wants the government to take action to increase the energy generated by renewables in Italy by at least 20GW each year.
Ultima Generazione is part of the A22 network of climate civil-disobedience groups active in several countries, such as Just Stop Oil in the UK, Stop Old Growth in Canada, Derniere Renovation in France and Declare Emergency in the United States.
