German police arrest Syrian suspect in Berlin Holocaust memorial attack

German police arrested Khalaf A. in Berlin on May 27 on suspicion that he helped enable the stabbing attack at the Memorial to the Murdered Jews of Europe in central Berlin, a case that now reaches beyond the man who carried out the assault. Federal prosecutors said the Syrian citizen was detained on a warrant issued May 19 and is suspected of aiding and abetting attempted murder and dangerous bodily harm.

Prosecutors say Khalaf A. was in contact with Wassim Al. M., spent the afternoon before the attack with him and encouraged him to carry out the plan. The assault took place on the evening of February 21, 2025, in the memorial’s stelae field in Berlin-Mitte, when Wassim Al. M. stabbed a man in an attack prosecutors tied to a radical Islamist and antisemitic mindset. The victim survived.

Wassim Al. M. was sentenced on March 5 by the Berlin Kammergericht to 13 years in prison for attempted murder and dangerous bodily harm, although that verdict was not final. The new arrest suggests investigators are still working through whether the attack was more than a lone act and whether there was planning, encouragement or other support behind it. In Germany, where responsibility for the Holocaust sits at the center of the state’s historical memory, those accomplice allegations carry particular weight.

The memorial itself is one of the country’s most visible symbols of remembrance. It opened on May 10, 2005, covers 19,073 square meters and consists of 2,710 concrete stelae. Its information center draws nearly half a million visitors a year, underscoring why any violence there reverberates well beyond the courtroom.

The attack also landed in the middle of a volatile political moment, just two days before Germany’s February 23, 2025 federal election, when immigration and security were already dominating debate. Antisemitic violence has remained a stark backdrop: Bundesverband RIAS recorded 8,627 antisemitic incidents in Germany in 2024, up 77 percent from 2023, and said 68 percent of documented cases were related to Israel and the war in the Middle East. RIAS Berlin documented 2,521 incidents in the capital last year. The arrest now deepens scrutiny of how Germany protects sites of memory while tracing extremist violence back to the people who help make it possible.
