Conor McGregor calls for "torture and death" for Dublin child stabbing suspect

Three children and two adults were injured - two of them critically - during a knife attack at a Dublin school in Parnell Square on Thursday.

The suspected assailant was detained by a number of people at the scene and held until police arrived. The authorities arrested the suspect, a 50-year-old man, whose specific motivation for the attacks is not yet understood. In this regard, police are keeping all lines of enquiry open.

Rumors quickly spread on social media that he was a foreign national, which has not yet been confirmed. This, according to the police, encouraged radical groups on the far right of British and Irish politics, to take to the streets to protest against the influx of immigrants into Ireland.

What has Conor McGregor said about the Parnell Square incident?

Conor McGregor was one such high-profile voice who has been accused of stoking the flames of anger and conflict.

"We are at war," was one of the many messages posted by McGregor.

The Notorious has been very active on social media for the past week, issuing such slogans since the conviction in the Ashling Murphy murder case that shocked the entire country.

The school stabbing drew a group of anti-immigrant protesters to the scene in Parnell Square and as the afternoon progressed into evening, the protests erupted into violence, especially on O'Connell Street.

The result of the riots were 13 shops looted, one tram and two buses burnt, 11 police vehicles damaged, several officers injured - one seriously - and 34 people arrested.

Irish Police Commissioner Drew Harris said these actions were carried out by far-right radicals.

"What we saw last night was an extraordinary outbreak of violence. These are scenes we have not seen for decades," he told a press conference.

"We have seen an element of radicalization that is damaging to our society."

"We have to assume that we will see more of these protests."

The riots were condemned by almost all political parties, including the main opposition Sinn Fein party.

Conor McGregor, for his part, seemed keen to add fuel to the fire, offering his take on what punishment should be handed out to the alleged attacker.

"Torture and death" for the detainee, the fighter demanded on Twitter.

"Innocent children were mercilessly stabbed by a mentally disturbed foreigner in Dublin today.... There is a grave danger among us in Ireland that should never be here in the first place, and no action has been taken to support citizens in any way with this terrifying event.

"Ireland for victory. God bless those attacked today, we pray."
