Facebook agrees to help schools tackle cyberbullies.

A deal was brokered at a meeting between senior Facebook executives and officials at the Department of Education.

Facebook has been under growing pressure after a number of disturbing incidents where students or teachers were targeted on social media sites.

In one case earlier this year,  Facebook repeatedly refused to remove an offensive photograph and text casting a slur on a teacher at the second-level Colaiste Chiarain, Croom, Co Limerick, stating that it did not believe it violated its standards on bullying and harassment.
