MOSCOW, Sept. 27 (Xinhua) -- Russian law enforcement officers have detained nine people suspected of raising funds for the Islamic State (IS) terrorist group, the Russian Investigative Committee and the Interior Ministry said Friday.

The detentions took place in Moscow City, Moscow Region, and the republics of Dagestan and Kabardino-Balkaria in North Caucasus, an Investigative Committee statement said.

According to investigators, one detainee joined the IS in Egypt and after returning to Russia in 2015 created a group of about 30 people, who took the oath of allegiance to the IS and agreed to contribute to financing the terrorist group in Syria and Iraq.

The organizer of the group used their bank cards to collect funds, which were later transferred to accounts of terrorists on a monthly basis, the statement said.

The Interior Ministry said in a statement that the organizer of the group is a native of Kabardino-Balkaria, and the group also includes natives of North Caucasus and Central Asian countries.
