German daily Sueddeutsche Zeitung says it has obtained a vast trove of documents detailing the offshore financial dealings of the rich and famous.

The Munich-based newspaper says it received the data from an anonymous source more than a year ago and shared it with over 100 news organizations.

Their work was coordinated by the International Consortium of Investigative Journalism, a nonprofit organization based in Washington.

Sueddeutsche Zeitung said Sunday the amount of data it obtained is several times larger than a previous cache of offshore data published by WikiLeaks in 2013 that exposed the financial dealings of prominent individuals.

The ICIJ says the latest trove contains includes nearly 40 years of data from a Panama-based law firm, Mossack Fonseca. The company didn't immediately respond to a request for comment.
