Ai Weiwei said the destruction of one of his works by Russian drones in an attack on the Ukrainian capital of Kyiv has brought it "full circle".

His installation, Three Perfectly Proportioned Spheres and Camouflage Uniforms Painted White, was made from Ukrainian military uniforms and had been on display in the city last year before being moved to a warehouse that was burned down in July.

He told the Berliner Zeitung newspaper the work had "fulfilled its purpose", adding: "Because I created it during the war, for Ukraine. Its destruction now brings things full circle."

The work was commissioned by Ukrainian art group Ribbon which described it at its unveiling as "a testament to both human and non-human victims of war".

It comes a few days after the country's ministry of culture said more than 4,500 cultural sites had been damaged or destroyed across Ukraine by Russian missile attacks.

The age of Illinois schoolboy Anderson Taylor when he set up his own museum setting the record for the world's youngest curator. He told Guinness World Records his natural history museum was inspired by a visit to the Staffin Dinosaur Museum on the Isle of Skye in Scotland, adding: "I've been into dinosaurs and fossils all my life."

The Art Institute of Chicago must be kicking itself at missing out on the chance of a blockbuster show.

KPop star RM credits the Midwestern institution with sparking his interest in collecting during a 2018 visit while on tour with his group, BTS, but it is the San Francisco Museum of Modern Art that snared the first-ever show of around 145 works from his collection.

How did they do it? Simple, they asked. He told the New York Times they were "really serious" about it from the outset and proved "they understood me — what I love and what I’ve been pursuing."

The show, which opens on October 3, includes work by artists including Kim Whanki, Chang Ucchin and Lee Daiwon and is likely to bring a whole new audience to the California museum with his fanbase including his 53.6 million followers on Instagram.

Its director Christopher Bedford said, with some understatement, the South Korean singer would bring "ideas about collecting and audience engagement that go far beyond what museums do conventionally".

Tributes have been paid to painter Mary Heilmann after her death in New York aged 86.

Her studio said it was "heartbroken" and said her life had been "marked by dedication to her artistic practice".

Brooklyn Rail co-founder Phong Bui said she had "profoundly inspired" a generation of young artists, while a spokesman for Hauser & Wirth galleries said she had "forged a singular position in contemporary art through a rigorous and pioneering approach to abstraction".

Born and raised in California, she was working as a sculptor when she first moved east but went on to make her name as an abstract painter and maker of colorful furniture.

What a difference a day makes.

Friday saw Italian police celebrate the recovery of three paintings by Paul Cezanne, Pierre-Auguste Renoir and Henri Matisse stolen earlier this year from a private museum near Parma.

24 hours later, they were launching an investigation into the theft of four pieces by 15th-century Renaissance master Antonello da Messina.

The works, including three panels from his Polittico di San Gregorio altarpiece, were taken from a museum in the Sicilian city of Messina with art historian Valentina Certo describing the theft as "a wound inflicted on the historical memory and cultural identity of the city".

Investigators are examining the possibility they were stolen on order for a dealer. It comes just six months after the Italian government paid $14.9 million for an Antonello masterpiece Ecce Homo with a view to putting it on public display.
