Nazi art thefts under summit spotlight
Jewish groups and representatives of 49 countries are meeting in Prague for talks on returning art and property stolen by the Nazis.
The Nazis stole an estimated 650,000 religious items and works of art from European Jews during World War II.
While much of the art has been returned, a great deal remains in museums and private collections.
The five-day conference in the Czech capital aims to assess efforts to return property and possessions looted by the Nazis to their rightful owners and heirs.
While countries such as Austria have stepped up restitution in recent years, critics say some central and eastern European states still have a long way to go.
They have been accused of putting up legal hurdles and a lack of political will, that critics argue make property and art restitution in some cases practically impossible.
