MIAMI — Hundreds of students have walked out of their Miami high school to protest gun violence after four current or former classmates were shot off campus.

The students chanted “no justice, no peace” Tuesday and carried “enough is enough” signs outside Northwestern Senior High School.

They staged the protest after the weekend shooting deaths of 17-year-old Kimson Green, a 10th-grader who was about to become a member of the National Honor Society, and 18-year-old Rickey Dixon, a former Northwestern student. Two other current or former classmates were wounded.

The shooting happened Sunday at an apartment complex in the Liberty City neighborhood, which is plagued by gun violence.

No arrests have been made.
