MOSCOW, May 24. /TASS/. The tribunal over Ukrainian nationalists from the Azov battalion will include several stages, with the first stage to take place in Mariupol, Donetsk People’s Republic head Denis Pushilin announced Tuesday.

"I believe we should not delay it [the tribunal], and a number of intermediate tribunals must be held before the main one, as it was after the Great Patriotic War. Before Nuremberg, there were Kiev and Kharkov tribunals and a number of others. Apparently, we will have the Mariupol Tribunal as one of the first ones," Pushilin said in a video footage, published in Russian journalist Vladimir Solovyov’s Telegram channel Tuesday.

Pushilin also said that "a number of countries preliminarily agreed to take part in the international tribunal." As for the Charter of the tribunal, it is being developed by relevant agencies, including Russian ones, he added.

Previously, Pushilin stated that Ukrainian nationalists must be tried by a tribunal, and speculated that this tribunal could be international. According to Pushilin, necessary documents, including the charter, are being prepared.

On May 20, Russian Defense Ministry spokesman Igor Konashenkov announced that Russian forces completely liberated the Azovstal plant in Mariupol, where remaining Ukrainian forces, including Azov nationalist battalion militants, were blocked. According to the Ministry, over 2,400 people laid down their arms.
