A SWISS museum has accepted a priceless collection of long-hidden art bequeathed to it by German collector Cornelius Gurlitt.

Kunstmuseum Bern's president Christoph Schaeublin announced in Berlin the museum would accept the collection but would work to ensure any art looted from Jewish owners by the Nazis is returned.

Bavarian authorities seized 1,280 items from Mr Gurlitt's apartment in Munich in 2012 while investigating a tax case. Mr Gurlitt later reached a deal with the German government to check whether any of the works were looted. Authorities said the deal is binding on any heirs.

One of Mr Gurlitt's cousins has filed a claim, which a Munich court said would have to be dealt with before the collection goes anywhere. Mr Gurlitt died in May.
