In a statement on
its website, the Houston Independent School District said police
were sweeping campuses as a precaution, but the threat did not
appear to be credible.
Class was to be held as normal on Thursday for its 213,000
students, the district said.
Miami-Dade County Public Schools also received a threat late
Wednesday, according to a statement on the district's website.
After consultation with state and federal law enforcement, it
was deemed "less than credible," it said.
The new round of threats came a day after the Los Angeles
Unified School District, the second largest in the nation,
abruptly canceled class for its more than 640,000 students after
receiving an email that said an attack with guns and bombs was
planned at multiple locations. The threat was later dismissed as
New York City public schools received a nearly identical threat
but dismissed the message and kept its schools open.
Parents in Houston were asked to be vigilant should they see
anything out of the ordinary on Thursday morning, the district's
Miami, which also has no plans to cancel classes, said parents
were encouraged to send their children to regularly scheduled
