The men, aged between 20 and 30 and allegedly members of banned groups, were accused of "organising a criminal group for participating in armed conflicts or warfare in other countries," a statement by the regional prosecutor's office in northern Sogd region said.
They were arrested in northern Tajikistan and "were planning to leave to participate in the Syrian war on the side of the armed opposition," it said, adding that they were suspected also of preparing to fight with Islamic State groups.
Tajikistan, which has been led since 1992 by former Soviet apparatchik Emomali Rakhmon, has arrested scores of people on suspicion of extremist activities in recent months.
