An eight-year-old girl was among the 22 people killed by a suicide bomber after an Ariana Grande concert at the Manchester Arena.
Saffie Roussos, a "beautiful little girl", was killed in the attack which ripped through the venue on Monday night.
In a statement released through Lancashire County Council, Tarleton Community Primary School headteacher Chris Upton said: "News of Saffie's death in this appalling attack has come as a tremendous shock to all of us and I would like to send our deepest condolences to all of her family and friends.
"The thought that anyone could go out to a concert and not come home is heartbreaking."
At least 59 people were wounded in the suicide attack as people left the concert.
A UK ambulance official says 12 children under age of 16 are among those injured.
The first victim of the attack, named earlier on Tuesday by her college, was 18-year-old Georgina Callander.
