Jeddah: A Saudi special court has sentenced two Shiite men to eight and nine years in jail, respectively, for taking part in protests in the Eastern Province, SPA state news agency said on Friday.

The first defendant was found guilty of joining three protests in the town of Awamiya, in the province’s Shiite Qatif region, it said.

He was also found guilty of having “anti-kingdom and anti-rulers pictures on his mobile phone... and of knowing dissidents in Qatif and covering up their activities”.

The second defendant, who was sentenced to nine years, was found guilty of taking part in “most demonstrations” in Qatif.

He was also convicted of “surfing dissident internet websites, and posting statements inciting opposition to the rulers... as well as calling for the release of prisoners”, SPA said.

The two defendants and the prosecution have decided to appeal the verdicts, it said.

There are an estimated two million Shiites in the kingdom of around 27.5 million people.

Shiite towns in the oil-rich Eastern Province have been rocked by sporadic violence as protesters clashed with police over what they say is the marginalisation of Shiites.

The unrest first erupted after violence between Shiite pilgrims and religious police in Madinah in February 2011.

Human rights groups say more than 600 people have been arrested in Saudi Arabia since the spring of 2011, most of them in Qatif. The majority has since been released.
