Shia Saudi clerics warned Sunday against taking up arms against the authorities in the Sunni-ruled kingdom, in the wake of sporadic violence that has rocked the country's Shia-dominate east.

Demonstrations in Eastern Province, where most of the kingdom's two million Shias live, erupted simultaneously with a protest movement in neighbouring Bahrain in 2011.

They took a violent turn in 2012 and clashes between police and protesters have so far killed 24 people, including at least four policemen, according to activists.

The 10 influential clerics from Eastern Province said in the statement received by AFP that "using violence and arms against the state is rejected and condemned".

They also warned Shia Muslims in the kingdom from "being lured into violence and extremism... which complicates matters and serves enemies."

The clerics insisted that religion demands achieving "security and stability in the country" and that "political violence destroys the nation".

Clerics who signed the statement included Hassan al-Saffar who is known for his role as mediator between Shia protesters and authorities in the past.

The statement follows several meetings between Khalid al-Safyan, governor of Qatif in Eastern Province, and a number of Shia dignitaries to try and ease tensions that have been brewing in the oil-rich east, activists said.

It also comes after Saudi Arabia published Friday a list designating "terror" groups, including the little-known Saudi Hezbollah Shia militant group and the Shia Huthi rebels in neighbouring Yemen.

In February unknown gunmen opened fire at a police station in the flashpoint village of Awamiya, in Qatif, wounding three policemen, a week after a firefight there killed two policemen and two wanted Shia activists.

In January, the US embassy in Riyadh warned its citizens against travelling to Awamiya after gunmen opened fire at the car of two German diplomats, who escaped unhurt.

Of more than 950 people arrested in the wake of the 2011 Arab Spring for involvement in the unrest in the province, 217 are still being held.
