All schools in the Los Angeles Unified School District (LAUSD) have been closed after officials received a bomb threat.
The FBI, Los Angeles Police Department and LA Sheriffs are all assisting the school investigating a "credible bomb threat".
LAUSD Superintendent Ramon Cortines told the press the threat was made to "not one school, two schools or three schools - it was many schools" and that he wanted each of his buildings searched immediately.
It remained unclear whether the bomb threat was credible. Reuters news agency reported an LAUSD spokesman had said the threat came from an email associated with an IP address in Frankfurt, Germany.
There are more than 640,000 students currently enrolled in LAUSD. More than 900 schools and 187 public charter schools are in the district.
