Belgium Police used water cannons and firemen fought back with foam and thrown objects after a labor protest got out of hand in the Belgian capital. About two-thousand firefighters were protesting close to the Belgian parliament. When they tried to break through security barriers, about 300 police tried to keep them back -- and that's when the trouble started. Police say three officers suffered facial injuries when the firemen pelted them with equipment and loose objects. Three firefighters were hospitalized, one of them for broken ribs after he fell off a water cannon. The firemen want better working conditions, earlier retirement, and better injury compensation.
