The six were charged by the lower criminal court with "misusing the right of free expression," said the regime in a statement posted online.
 

The six Twitter users were accused of writing remarks "undermining the values and traditions of Bahrain's society towards the king on Twitter", according to the statement, which did not identify the people who were accused.
 

Activists in Bahrain, the scene of an uprising that began two years ago against the ruling monarchy, use Twitter as a platform to report what they describe as regime "violations" against them.
 

Nabil Rajab, a prominent activist who heads the Bahrain Centre for Human Rights, has been in custody since June 6 on charges of insulting members of the majority Sunni community via Twitter.
 

The avid Twitter user was also accused of insulting the security forces in postings that he admitted came from his account on the microblogging website.
 

Another blogger, opposition activist Ali Abdulemam, has surface in London recently, after two years in hiding. He had been sentenced to 15 years in prison in absentia, but managed to escape the island kingdom.
 

A total of 80 people have been killed in Bahrain since the protests erupted in February 2011, according to the International Federation for Human Rights.
 

Strategically located just across the Persian Gulf from Iran, Bahrain is home base to the US Navy's Fifth Fleet and is also a major offshore financial and services centre for its Arab neighbours in the oil-rich Persian Gulf.
