Mr Farry was speaking as Kilmaine Primary School and Nursery Unit was evacuated on Friday morning, along with schools in Omagh and Armagh. It follows threats to seven schools, including in East Belfast, Bangor and Larne, on Tuesday (May 24).
“Whoever is behind these threats needs to stop immediately,” said Mr Farry.
“It is beyond any reason or logic for people to send such threats, particularly to primary schools where so many young people will be affected and have their education significantly disrupted.
“Whatever goal those behind the threats are looking to achieve will not be helped by these malicious actions. My thoughts are with all those affected and I wish to commend staff at the schools, who have acted with bravery to ensure the safety of the pupils.
“I urge anyone with information about these incidents to contact police immediately.”
