ZURICH—Armed robbers broke into a Zurich museum on Sunday and made off with artworks worth $100 million, the Associated Press reports. Three men wearing ski masks and dark clothing walked into the E.G. Buehrle Collection, a private museum, with pistols, forced museum staff to the floor, and took four masterpieces: Claude Monet's Poppy Field at Vetheuil; Edgar Degas's Ludovic Lepic and His Daughter; Vincent van Gogh's Blooming Chestnut Branches; and Paul Cezanne's Boy in the Red Waistcoat. Witnesses said the robbers loaded the paintings into a white vehicle parked in front of the museum and sped off. The news came just days after Swiss police reported that two Pablo Picasso paintings, Tete de cheval and Verre et pichet, were stolen from an exhibition near Zurich.
