The Kremlin’s spokesperson has made an unverified claim that a Ukrainian sabotage group has crossed into Russian territory.Dmitry Peskov said Russian troops and intelligence officials were taking steps to eliminate the group, which he said entered the Belgorod region bordering Ukraine. Media reports quoting Ukranian military intelligence say they were in fact Russian citizens from two armed groups, not Ukrainians. DW and other media sources have not been able to verify the claims of either side.
