Thirty-three people were injured here yesterday when riot police and protesters clashed as police tried to prevent an unauthorized rally organized by the Committee for the Unemployed. Baton-wielding police hit dozens of people who had planned to pelt the Parliament building with eggs and tomatoes to show their disappointment over the way the government was dealing with unemployment in Bahrain. Most of the injuries were the result of police action. Thirty-two injured were discharged from hospital shortly after they arrived. A police officer was also injured in the clashes.
