The Islamic State (IS) has claimed responsibility for a factory fire in the Moscow suburbs last month, an online jihadist monitoring organization reported.
The fire, which erupted on Nov. 14, was allegedly an act of arson by an IS supporter, the SITE Intel Group wrote on Twitter.

Fire crews worked around the clock for several days to extinguish the blaze at a furniture factory in Losino-Petrovsky.
Government investigators have yet to confirm the cause of the fire, which reportedly began in the building's basement.
No one was injured as a result of the blaze.
IS has previously released videos threatening attacks on Russian soil, warning President Vladimir Putin that IS would "kill you in your homes."
The Islamic State is a terrorist group banned in Russia.
