Chilling footage has emerged of the laboratory where alleged jihadists prepared to detonate bombs dubbed "Mother of Satan" on Moscow shopping centres and trains, security officials claimed.
A video of an apparent bomb-making factory outside the capital shows how ingredients for improvised explosives were seized.
It comes as Russia's Federal Security Service (FSB) said four suspects, including two would-be suicide bombers, were arrested.
Intelligence sources claimed ISIS ringleaders in Syria had given orders for a terror attack.
The cell allegedly planned to unleash a series of bombing atrocities on crowded transport and shopping locations across Moscow.

Disturbing evidence of a powerful arms cache including assault rifles, grenades, and components for hydrogen peroxide bombs dubbed "Mother of Satan" was provided by the FSB.
The nickname was given to indicate the extreme power of the explosives.
The pictures and video indicate the factory was set up at a house on the outskirts of Moscow with fears more could be discovered.
"The laboratory was located in a garage in Moscow region," said a secret services source.

"They were making bombs by evaporated explosives from old weapons, adding TNT and gun powder they purchased and attaching detonators to this explosive mixture.
"It cannot be excluded that there were other laboratories elsewhere."
An FSB official cited by Interfax said: "An urgent test of the substance seized from the detained terrorists revealed triacetone triperoxide, a very dangerous primary explosive."
This is peroxide-based and also known as TATP, believed to have been used by terrorist Salman Abedi in Manchester, along with attacks in Paris and Brussels.

The FSB named the suspected ringleaders as Tajikistan citizens A.M.Shirindzhonov and T.M.Nazarov - both based in Syria.
One suspected suicide bomber detained in Moscow was named as Siyovushi Davronzoda, aged only 17.
He told a court in Moscow: "I admit my guilt."
Two others were named as Sulaimon Burkhonov, who also admitted his guilt, and Davlater Khodzhiyev.
The FSB said the suspects "intended to carry out a series of terrorist attacks in crowded places, including on transport facilities and large shopping areas of Moscow".
The planned blasts were to be undertaken "with the use of terrorist suicide attackers and powerful explosives".
The agency - once headed by Vladimir Putin - said: "A laboratory manufacturing explosive substances and improvised explosive devices was discovered and disposed of in the Moscow region."
It is estimated that more than 4,000 Russian nationals, mostly from predominantly Muslim regions, have fought alongside IS militants in Syria.
