Ukraine is to file a claim at the International Court of Justice against Russia for supporting terrorism, Ukrainian Justice Minister Pavlo Petrenko has said.

"The next year will be devoted to the initiation of a large-scale lawsuit at the International Court of Justice through which Ukraine will sue Russia under the convention [for the suppression of] the financing of terrorism," Petrenko told Channel 5 on January 5.

The minister said that the evidence had already been gathered, the pre-trial process of communication with the Russian side was about to end, and "we'll go to court."

Petrenko also said that state-owned Oschadbank, and oil and gas giant NJSC Naftogaz Ukrainy were individually suing Russia at the Arbitration Institute of the Stockholm Chamber of Commerce.

He also added that over 700 Ukrainians – an their number was growing every day – had filed private lawsuits at the European Court of Human Rights against Russia's annexation of the Crimea and aggression in Donbas.

In his words, rulings on the first cases may be announced by the end of 2016.
