NEW YORK, NY (AP).- A decades-long dispute between Russia and an Orthodox Jewish group over ownership of holy texts collected for centuries by influential rabbis and seized by the Soviet Union has jolted the U.S. art world, threatening an end to major cultural loans between the two countries. Russia has already frozen art loans to major American institutions, including the Metropolitan Museum of Art and the Houston Museum of Natural Science, fearing that its cultural property could be seized after the Brooklyn, N.Y.-based Chabad-Lubavitch movement won a lawsuit in U.S. District Court in 2010 compelling the return of its texts.
