The number of people killed in the attack on Crocus City Hall has risen from 133 to 137, Russia’s Investigative Committee said on Monday.

Among the dead were three children, the committee said, adding that 62 bodies have been identified so far.

People have been gathering near the concert venue, northwest of Moscow, on a day of national mourning in Russia.

Blindfolded concert attack suspects led into investigative agency HQ

Suspects in the Crocus City Hall shooting have been brought to the Russian Investigation Committee’s headquarters in Moscow.

Footage released by the committee shows Russian authorities dressed in camouflage and balaclavas grabbing and pushing at least three men, who appear to be blindfolded, into the building.

As the video continues, two of the men could be seen with their heads pressed against a wall and their hands cuffed behind their backs.

The footage comes after Russian media broadcast videos purporting to show the violent arrest and interrogation of suspects on a roadside in Bryansk yesterday.

In footage shared by regime-aligned Telegram channels, a man was marched out of a forest, his face covered in blood from what appeared to be an ear injury, before struggling to speak in Russian.

Another video, this time published by Russian state TV editor Margarita Simonyan, showed a man lying on his stomach with his hands bound behind his back, his chin resting on the boot of a figure in camouflage uniform.
