MOSCOW (Reuters) - Russia's environmental watchdog said on Thursday that it had filed a lawsuit against a power unit of mining giant Norilsk Nickel GMKN.MM to claim 148 billion roubles ($1.96 billion) in environmental damage caused by a fuel leak earlier this year.
The watchdog had previously asked Nornickel to pay this sum voluntarily.
Nornickel did not immediately reply to a Reuters request for comment.
