The Catholic Archbishop of Dublin Diarmuid Martin has strongly condemned those involved in the drug trade and said that gangland violence must stop.
He was speaking during a 'World Day of Peace' Mass in Dublin.
President Michael D Higgins and his wife Sabina were among the many dignitaries at St Teresa's Church in Dublin's Clarendon Street today.
In his homily, Archbishop Martin said there was a now dangerous culture of violence in Ireland that was hard to understand.
