Two Bulgarians, three Russians and one Moldavian have been indicted on terrorism charges and will face a Czech Court.

The Russian RIA-Novosti agency reports that the trial would start within a month. If convicted the defendants could be jailed for up to 10 years.

In May 2011, special task force of the Czech police arrested eight people, including the two Bulgarians, on suspicions of terrorism.

The detainees are said to be part of an organized extremist group with ties with the Northern Caucasus region, Czech media reports.

They are charged as accessory to terrorist activities, supplying extremists with fake documents, weapons and explosives. The group had been operating in several countries.

The names of the Bulgarians have not been released.

Six are held in jail in the Czech Republic and two – in Germany.

During one arrest, the authorities were able to locate a secret terrorist base with extremist literature, automatic guns, grenades, and a large amount of cash. It is believed the detainees are associated with the Dagestan Djamaat Shariat group.

The investigation dates from the middle of 2008, when Czech special services have been alerted that supporters of the group were acting in the country. In the beginning of April, the authorities have received information some are getting ready to leave the Czech Republic and decided to act.

The operation began on April 6 when two of the group's members were in Germany.
