Police said the detained men were under the “ideological influence” of another Uzbek man who was a member of the Jamaat al-Tawhid wal-Jihad group comprised mostly of Central Asians.
They planned to finance the group and join it, police said in a statement, Reuters reported.
Thousands of people from the predominantly Muslim ex-Soviet region joined various militant groups in Syria and Iraq when Daesh (ISIL or ISIS) temporarily seized part of their territory.
