Russia's security service said Tuesday it had detained five suspects with ties to the Islamic State group jihadist group who were plotting to carry out attacks in the country.
The FSB security service said in a statement it had "thwarted the activities of a group created to perpetrate crimes of a terrorist and extremist nature" in Moscow and the Caucasus region of Ingushetia.
"Five members of this criminal group were detained as a result of an operation," the FSB said, without specifying when or where the suspects had been apprehended.
Two homemade bombs, five firearms and ammunition were recovered at the suspects' residence, the statement said.
In October Russian security forces killed six Islamists in the volatile North Caucasus region of Ingushetia.
The FSB said Saturday it had detained 10 people with alleged links to Islamic State group on suspicion of plotting armed attacks in Moscow and Saint Petersburg.
It said the suspects, detained in an operation in conjunction with the ex-Soviet Central Asian states of Tajikistan and Kyrgyzstan, had admitted to contacts with IS leaders.
