Saudi Arabia not to allow any demonstration on her soil
The kingdom banned all demonstrations saying they contradicted Islamic laws and society values, according to a statement issued by the Interior Ministry.
The new clampdown came a day after about 100 members of the Shia minority staged a protest in the western region of the kingdom.
"Security forces are authorised to act against anyone violating the ban," the statement said.
The restrictions come as a group of influential intellectuals urged King Abdullah to adopt far reaching political and social reforms.
They said the country`s rulers should take a lesson from the uprisings in Tunisia, Egypt and Libya and listen to the voice of disillusioned young people.
The group included renowned Islamic scholars, a poet and a former diplomat.
Like Egypt and Tunisia, social networking site Facebook has a page calling for a "March 11 revolution` in Saudi Arabia.
The message posted on Facebook calls for ousting of "regime of al-Saud clan".
Meanwhile, the Organisation of the Islamic Conference (OIC) has backed the call to the UN to enforce a no-fly zone over Libya.
An emergency meeting of the 57 member OIC said "we join our voice in the voices asking for no-fly zone over Libya and we call on the Security Council to do its duty in this regard."
The statement was issued by secretary general of OIC Ikmeleddin Ihsanoglu.
