Isis has executed five more Russian nationals after accusing them of "spying" in its territories, according to Russian media reports.
Last week, a video was released by the militant group showing a man dubbed the Russian "Jihadi John" purportedly executing a "Chechen spy".
The executioner has been identified by officials in the North Caucasus as Anatoly Zemlyanka. The Chechen leader Ramzan Kadyrov reportedly wrote on Instagram that the 28-year-old was an ethnic Russian and wanted by the police.
And on Tuesday, LifeNews quoted security sources in the region as saying another five Russians had been executed by Isis on similar charges. Their identities are unknown.
