(Updates with details on other school districts receiving threats)
Dec 17 (Reuters) - Two Indiana school districts closed on Thursday amid reported threats directed at schools there, while large school districts in Texas and Florida said they would hold classes after deeming threats made against them to not be credible.
School officials in the Indiana cities of Danville and Plainfield cited concerns about the safety of students and staff in announcing the closures of schools, which comes two days after officials in Los Angeles canceled classes for 640,000 public school students over a threatened attack with bombs and guns that was later deemed a hoax.
New York City public schools received a nearly identical threat but dismissed the message and kept schools open.
"A threat has been directed to the high school, and the safety and security of all students is our highest priority," officials in Plainfield, Indiana, said on their website, adding they were working with public safety officials in an ongoing investigation.
School districts covering Dallas, Houston, Miami and Fort Lauderdale said they had received threats of violence similar to those made against schools in New York City and Los Angeles this week but had no plans to close on Thursday.
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.
Parents in Houston were asked to be vigilant should they see anything out of the ordinary on Thursday morning, the district's statement said. (Reporting by Susan Heavey, Megan Cassella, Colleen Jenkins and Suzannah Gonzales; editing by Franklin Paul and Chizu Nomiyama)
