Feb. 9 (UPI) -- A series of bomb threats, which turned out to be hoaxes, caused government buildings and dozens of schools in Ohio to close on Monday morning.

Officials in Columbus and Springfield confirmed that schools in both cities were closed for the day, as was the Ohio Statehouse and Greater Columbus Chamber of Commerce, among others, after a series of bomb threats were delivered to them.

Law enforcement determined that there was "no immediate or credible threat to the public" in Springfield, Mayor Rob Rue said later in the morning in a statement.

Calling the threats "despicable," Ohio Gov. Mike DeWine said that suspicious packages were found near at least two of the threatened locations and revealed that some of the threats made reference to more than 10,000 Haitian immigrants in the state, the New York Times reported.
