KIEV, July 10 – Oschadbank plans to sue Russia over the losses it incurred due to the occupation of Crimea for at least $670 million, according to Andriy Pyshny, chairman of the state-owned savings bank.

"The very preliminary sum is $670 million. This does not take into account many factors that could considerably expand the claims," he wrote on his Facebook page on Thursday.

The banker said that the satisfaction of the claims will take years.
