The politician said this in an interview with NBS.

“I can’t guarantee anything, it depends on the investigation,” Peskov commented on the journalist’s question about whether the history of British and Moroccan mercenaries Sean Pinner, Aiden Aslin and Brahim Saadoun would repeat itself in the situation with American prisoners of war.

Earlier it was reported that a court in the Donetsk People's Republic handed down death sentences to British citizens Sean Pinner and Aiden Eslin, as well as a Moroccan citizen Saadoun Brahim, who fought on the side of Ukraine. 

The convicts plan to appeal against the court decision on their execution.
