The famous Mona Lisa painting has fallen victim to yet another protest attack, with activists hurling pumpkin soup over the 16th century masterpiece.

The protestors, who represent a French environmental protection group, took to the painting to raise awareness for the issue of sustainable food.

Newstalk ZB Europe correspondent Gavin Grey says the group is calling on food to be more accessible.

"Basically, what the want is a food card worth roughly $270 NZD to be given to citizens each month to be used on food."
