Witnesses of the Moscow attack say a gang beat them with metal rods and stabbed them repeatedly with a knife.
The victims were working as street cleaners in the Russian capital.

Police are hunting the three men who they believe carried out the attack.
They were last seen escaping towards the nearest metro station.
