BONN, Germany (AP) _ Several hundred students pelted police with eggs, firecrackers and stones Thursday in a wave of protests over Germany's education budget.

The militant group within a larger, peaceful rally of 30,000 students tried to storm government buildings, but police with clubs held them back.

Several students and officers were slightly injured. Two students were arrested and face charges of breaking and entering, police said.

Others distanced themselves from the violence.

``If we're too radical, we don't succeed in anything except turning the population against us,'' said electrical engineering student Sophia Hatzelmann.

It was the second rally in Bonn in as many months as students press the government to keep Germany's cherished tuition-free education system intact.

Students say years of state and federal budget cuts have left university classrooms overcrowded, textbooks outdated and subsidies for living expenses meager.
