The fatal stabbing of a teacher in front of her pupils has prompted condolence messages from as far afield as Australia.
Ann Maguire, 61, was killed at Corpus Christi Catholic College in Leeds on Monday.
Tributes and flowers were left at the school gates and former pupils earlier attended a Mass for Mrs Maguire.
A 15-year-old pupil is being questioned by detectives, while the school is open as normal.
