| Kuwaiti police tussle with protesters earlier this week |
Protesters had massed in several parts of the capital city, preparing to march on government buildings.
Security forces were sent out to surround each of the groups, giving them minutes to leave.
When the groups didn't leave in time, police fired tear gas, and in some cases concussion grenades into the massed people.
Injuries have been reported, but in what numbers is not yet known.
Officials of the Interior Ministry had warned that no protests would be allowed.
