Schools were evacuated across Italy on Wednesday following a series of hoax bomb threats, but Italian Prime Minister Giorgia Meloni said there was no "concrete danger".
The exact number of schools affected remains unclear, as the emails were sent to hundreds of institutions, with individual schools deciding whether to evacuate following advice from local police, according to media sources.
Authorities are investigating the origin of the messages, although police have not confirmed the email address from which they were sent.
This is a developing story and more information will follow.
