Swiss police have seized paintings belonging to the Pushkin Museum. “The 25 paintings – part of a collection on loan to an exhibit in Martigny – were seized on behalf of a local firm which claims Russia owes it money. The Pierre Gianadda Foundation display, which included works by Manet, Renoir, Picasso and Matisse, was said to have been insured for $1bn (£597m). The company, Noga, said it was owed money for food deliveries in the 1990s.”
