“We will not give up our right to peacefully demonstrate,” the flier says.
“We will express our solidarity with the Libyan people who are living the hardship of their revolt against the oppressive and unjust system of Muammar Gaddafi,” it added.
Also in the eastern Qatif region, people are planning to hold a rally on Friday in support of the Libyan revolution and the uprising in Bahrain.
Thousands of people have said they are prepared to attend the protests after Saudi youth named March 11th the Day of Rage on the social networking website, Facebook.
On Wednesday, Saudi King Abdullah suddenly announced a series of benefits for his citizens following revolutions in Tunisia and Egypt.
King Abdullah introduced a package of social and economic overhaul amounting to USD 10.7 billion.
He also granted pardon to some prisoners indicted in financial crimes and ordered the implementation of a 15-percent pay hike for state employees as well as an increase in the cash available for Saudi housing loans.
Analysts believe the huge hike in benefits introduced by the Saudi King is actually intended to avert an uprising in the country.
