Los Angeles area students are returning to class under a cloud of apprehension after a summer of immigration raids and amid worries that schools could become a target in the Trump administration’s aggressive crackdown.

More than 500,000 students in the Los Angeles Unified School District began a new school year Thursday with concerns and fear amid the ongoing immigration raids.
