Five people were wounded, including three children, in a stabbing outside a primary school in Dublin, Ireland this afternoon (Thursday).

A five-year-old girl and a woman in her 30s were seriously wounded in the stabbing. A five-year-old boy, a six-year-old girl, and a man in his 50s suffered less serious injuries.

Police say that the man in his 50s is a person of interest in the stabbing and that they are not looking for anyone else in connection with the attack at this time.

Superintendent Liam Geraghty told reporters that the incident appeared to be a "standalone attack" and that it was not being treated as an act of terrorism. However, police are not ruling out any motive yet.

Witnesses stated that a man armed with a knife arrived at the school and began attacking children as they left the building. Several bystanders intervened and disarmed the attacker.

Following the attack, protestors gathered near the area and clashed with police. A police car was set on fire and bottles were thrown at officers.

The school where the attack occurred teaches lessons in Irish Gaelic.
