Investigators in Germany have started reviewing an arson attack on Sunday against the home of Andreas Büttner, commissioner for combating antisemitism in the state of Brandenburg, where assailants set fire to a shed at his property in Templin — a town located approximately 43 miles north of Berlin — and spray-painted an inverted red triangle, the symbol of support for the Islamist terrorist group Hamas.

“My thoughts are with Andreas Büttner and his family,” Israeli Ambassador to Germany Ron Prosor posted on X. “Knowing him as I do, after this attack he will only stand up even more resolutely against antisemitism. For the radical part of the ‘Palestine solidarity’ movement is not only antisemitic, but terrorist.”

Prosor explained the significance of the red triangle, writing, “Attacks on those who think differently and attempted murder: That is what the Hamas triangle stands for — in Gaza as in Brandenburg. And the hatred of Israel goes hand in hand with hatred of our democracy. The rule of law must smash these terrorist organizations — and indeed, before they strike again.”

The red triangle vandalism appeared “on the neighboring house’s door entrance,” according to Germany’s DW media.

The home of Germany’s antisemitism commissioner, Andreas Büttner, was set on fire overnight in a targeted attack.

His family was inside the house at the time.

“The symbol speaks a clear language. The red Hamas triangle is an internationally known sign of jihadist violence and antisemitic incitement,” Büttner said. “Anyone who uses such a thing wants to intimidate and glorify terror. This is not a protest, it is a threat.”

According to Büttner, his family was inside the house at the time of the arson, the second attack against him in the past 16 months. His car was previously vandalized with swastikas.

Büttner released a statement on X.

“This attack represents a massive escalation,” he wrote. “It is directed against me personally, against my family, and against my home. At the same time, it is an expression of hatred and intimidation. I will not be intimidated by this. Anyone who believes that they can achieve something through violence, arson, or threats is mistaken. Such acts do not lead to me becoming quieter or questioning my commitment — they strengthen me in what I do. I ask that you give us the necessary peace today and refrain from further inquiries at the present time.”

Brandenburg’s Prime Minister Dietmar Woidke also condemned the violence, saying that “violence against people or things is and remains absolutely unacceptable. The police have started the investigation, and I hope that the perpetrator or perpetrators will be caught quickly.”

Jochen Feilcke, chairman of the German-Israeli Society Berlin and Brandenburg, described the attack “as where Hamas’s terrorism was applied on a small scale, including the Hamas triangle, in order to ultimately intimidate all people who defend themselves against increasing antisemitism in Berlin and Brandenburg.”

“Especially the parties of the left camp have every reason to deal with it, because they tolerate this mood or still fuel it,” Feilcke told Tagesspiegel. “They are so jointly responsible for when debates turn into violence.””

The Jewish Virtual Library describes how the inverted red triangle symbol was originally used by the Nazis to designate political prisoners.

“According to Holocaust historians, this triangle was part of a dehumanizing classification system, where each prisoner was identified by different colored triangles depending on their ‘crime,’” writes Or Shaked, deputy director of the Jewish Virtual Library. “The red triangle identified political dissidents, including socialists and communists. After World War II, the survivors of Nazi persecution and their families reclaimed the red triangle as a symbol of resistance to fascism.”

Shaked explains the revival of the symbol in recent years, noting that following Hamas’s Oct. 7, 2023, massacre across southern Israel, the symbol began appearing in Hamas-produced propaganda, marking Israeli military targets. Its use spread to anti-Israel protests, particularly on college campuses and social media, where demonstrators use it to show solidarity with Palestinians.
