FERGUSON, Mo. (AP) — Students at three high schools in the Ferguson area have walked out of classes to express their concerns about the grand jury's decision not to indict Darren Wilson, the police officer who fatally shot 18-year-old Michael Brown in August.

Hundreds of students at McCluer, McCluer North and McCluer South-Berkeley high schools walked out on Tuesday and marched, chanting slogans. It was their first day back in class. Thanksgiving break was extended a day due to bad weather Monday.

Teachers joined students. The Ferguson-Florissant School District provided buses to pick up the students after the protest and return them to classes. The students were back in class by 1:30 p.m.

Similar walkouts were staged Monday across the country, including at Clayton High School in St. Louis County.
