Russia says killed IS militants planning attack on Moscow

Russia's FSB security service said Thursday it had killed Islamic State militants who were planning a "terrorist attack" on a Moscow synagogue, Russian state news agencies reported.

The FSB said an IS cell based in Kaluga, southwest of Moscow, had been planning to shoot Jewish worshippers at a synagogue in the capital.

"While being arrested, the terrorists put up armed resistance to the Russian FSB officers, and as a result were neutralised by return fire," the TASS news agency quoted the security service as saying in a statement.

"Firearms, ammunition, as well as components for the manufacture of an improvised explosive device were found and seized," it added.

The Zvezda news outlet, close to Russia's army and security apparatus, published an FSB video appearing to show two dead bodies inside a house, alongside guns, ammunition and knives found during a search.

The FSB did not say how many people were killed in the operation.

It said the fighters were members of the Afghan branch of Islamic State, but did not state their citizenship.

Russian authorities frequently announce the thwarting of planned attacks by suspected Islamist groups.

Earlier this month the FSB said it killed six suspected IS fighters in the Muslim-majority southern region of Ingushetia.

Tensions between Russia's Muslim and Jewish communities have flared at times during the Israel-Hamas war.

Last October, protestors stormed an airport in Dagestan, another Muslim-majority region in the Caucasus, after a plane arrived from Tel Aviv.
