Activists splash soup on glass-protected Mona Lisa

PARIS, France — Two protesters on Sunday hurled pumpkin soup at the bullet-proof glass protecting Leonardo da Vinci's "Mona Lisa" in Paris, demanding the right to "healthy and sustainable food", an AFP journalist and the museum said.

The action, which comes as French farmers protest across the country, is the latest in a string of similar attacks against artworks to demand more action to protect the planet.

Two women on Sunday morning flung streams of orange-coloured soup onto the glass protecting the smiling lady to gasps from the crowd in the French capital's Louvre museum, according to an AFP journalist at the scene.

"What is more important? Art or the right to healthy and sustainable food," the activists asked, standing in front of the painting and speaking in turn.

"Your agricultural system is sick. Our farmers are dying at work," they said, before security staff evacuated the room.

The Paris prosecutors office said both activists had been detained.

The Louvre museum said the women had hidden the pumpkin soup in a coffee thermos.

Small quantities of food are allowed inside the museum, though eating is not allowed in the exhibition rooms.

The museum said the artwork had suffered "no damage", and the room housing the masterpiece had re-opened to the public after closing for around an hour.

A group called Riposte Alimentaire ("Food counterattack") claimed responsibility for the stunt.

They said the soup throwing marked the "start of a campaign of civil resistance with the clear demand...: social security of sustainable food".

They referred to a survey of 996 people last year by the Ipsos polling group that found that one in three French people were not always able to afford enough healthy food for three meals a day.

Member Till Van Elst said the group wanted the state to allow people to buy selected food items at reduced rates through a specialised social security card. Under the scheme, democratic assemblies would choose the food to be subsidised.

"We want citizens to really be able to decide what is in their plates," he told AFP.

Culture Minister Rachida Dati criticised the soup attack.

"The Mona Lisa, as our heritage, belongs to future generations. No cause
