A “radicalized teenager” shot dead two people outside a gay bar in Slovakia’s capital, Bratislava, Prime Minister Eduard Heger said.

The gunman killed two people and wounded another near the Teplaren bar in the city center Wednesday evening, police said. The suspected attacker was found dead Thursday morning, officers added.

“I strongly condemn a murder of two young people shot dead in Bratislava last night by a radicalized teenager,” Heger wrote on Twitter.

“No form of white supremacy, racism and extremism against communities, incl. LGBTI, can be tolerated,” he added.

Police said they have not yet determined the motive behind the shooting and asked the public for patience as they looked into the possibility that it was a hate crime.

Slovak media reported the main suspect had posted messages with the phrases “hate crime” and “gay bar” hashtagged on Twitter. The Dennik N news website said the attacker had posted a manifesto against the LGBT and the Jewish communities before the killings.

The Duhovy Pride Bratislava group said it was shocked by the attack, while Slovak President Zuzana Caputova offered her support to the LGBT community.

“I want to say to the LGBT community, it is not you who don’t belong here, it is not you who should be afraid to walk in the streets. It is hate that does not belong in Slovakia,” she told reporters after visiting the scene of the attack.

European Commission President Ursula von der Leyen said her thoughts were with the families of the victims.

“These abhorrent murders are a threat to our societies built on respect and tolerance. The E.U. is committed to helping fight hate crime and speech in all form. We must protect the LGBTIQ community,” she added.
