LA shutdown: all schools in Unified School District closed due to 'electronic threat'
All schools in the Los Angeles Unified School District (LAUSD) have been ordered closed due to 'an electronic threat'.
Officials said they are still analysing the threat, adding that the action was being taken out of an abundance of caution.
Los Angeles school superintendent Ramon Cortines said the threat, via 'electronic message', concerned "many schools" in the district, with reference to backpacks and packages.
"I think it's important I take the precaution based on what has happened recently and what has happened in the past. I'm not going to take the chance with the life of a student."
Schools would remain closed until the threat was cleared, which they expected to happen by the end of Tuesday.
The LAUSD tweeted: "Students that have arrived at school will be with staff until parents or guardians can be contacted."
The Los Angeles Unified School District, the second-largest in the United States, has 640,000 students in kindergarten through to 12th grade and more than 1,000 schools.
The district spans 720 square miles (1,865 square kilometers) including Los Angeles and all or part of more than 30 smaller cities.
"We need to cooperation of the whole of Los Angeles today," said school board President Steve Zimmer.
"We need families and neighbours to work together with our schools and with our employees to make sure our schools are safe throughout today."
