CEOAFRICA gathered that the German officials have confirmed that some unknown artworks were found in a trove of Nazi-looted art in Munich.

According to source, the works had been seized from private individuals or institutions.

They include works by Renoir, Picasso, Chagall and Toulouse-Lautrec.

Prosecutors said the issue of ownership was still being clarified over the works, which were found in 2011.

The total value has been estimated at about 1bn euros (£846m; $1.35bn).

Reinhard Nemetz, head of the prosecutors' office in Augsburg, said that 121 framed and 1,258 unframed works had been seized in the flat of Cornelius Gurlitt in Munich.

It was not yet clear if any offence had been committed, he added, stressing that the legal position was extremely complex.

According to an Art expert Meike Hoffmann, some of the works were dirty but they had not been damaged.
