In Ukraine, Group DF has confirmed this week's arrest of owner Dmitry Firtash in Vienna, but blamed his detention on a misunderstanding.
In a short statement, the company said that according to its information: "The actions of Austria's law enforcement authorities...are neither related to the events happening in Ukraine, nor to the group's activities in Europe or [the] USA. They are related to an investment project dating back to 2006."
The ammonia and urea producer added: "We are convinced that this incident is the result of a misunderstanding, and that this situation will be resolved in the nearest future.
"Group DF will provide further information on this subject in due course."
