MOSCOW (Sputnik) – According to the broadcaster 9News, the schools evacuated over the phone calls are located in the states of Victoria, Queensland and New South Wales (NSW).
"There is clearly a pattern of hoax calls designed to cause disruption and attract media attention," the spokeswoman from the NSW Police Force said.
She added that the police have been investigating the calls.
"The threats appear to come from overseas with no credible evidence they could be carried out here," the spokeswoman said.
The news comes a day after at least six schools were evacuated in Sydney after receiving violent threats.
