> The signals coming from Russia are concerning for Ukraine.
"Nazi criminals should not be exchanged," the speaker of Russia's lower house of parliament, Vyacheslav Volodin, said on Tuesday. "We should do everything to ensure they are put on trial."
Another senior politician, Leonid Slutsky, went further, calling the evacuated combatants "animals in human form" and saying they should be executed.
And the Donetsk separatist leader, Denis Pushilin, suggested that Ukrainians who are found to be "neo-Nazi war criminals" should face an international tribunal.
