Russian security forces detained four individuals in Dagestan linked to the Moscow Crocus City Hall terror attack.

The detainees are accused of supplying weapons and financing, with one confessing to weapon delivery.

A video released by the FSB shows a suspect admitting to plotting an additional attack in Kaspiysk, Dagestan.

The detainees are identified as foreign nationals and are connected to a group claiming allegiance to the Islamic State.

President Putin has suggested Ukraine and Western countries are complicit, a claim they reject.

A Moscow court has mandated a two-month pretrial detention for a Tajik national suspected of funding the attackers' housing.
