Russia shows underground tunnels inside Mariupol's steel plant and traces of foreign mercenaries

The Russian military showed the underground tunnels beneath the Azovstal steel plant where Ukrainian soldiers held out during the siege of Mariupol. More than 2,500 Ukrainian troops surrendered late May from the steel mill are being held prisoner. But Russian lawmakers had debated over the possibility of a ban on the exchange of the “nationalists” Azov regiment for Russian servicemen, while the speaker of the State Dumacalled for them to stand trial. 400 foreign mercenaries had reportedly fought and hidden inside the Azovstal. And Russian Foreign Ministry claimed the number of “foreign mercenaries” being used by Ukraine “decreased by half by the beginning of June”.
