Boulder Firebombing Suspect To Plead Guilty In Deadly Pro-Israel Attack
Mohamed Sabry Soliman will plead guilty Thursday to murder and other state charges in the June 1, 2025, firebombing of a pro-Israel rally in Boulder, Colorado.
The attack killed 82-year-old Karen Diamond and injured about a dozen people. Court documents say Soliman will enter the plea at a Thursday hearing. He also faces separate federal hate-crime indictments, and prosecutors are weighing the death penalty.
The episode traces back to the Oct. 7, 2023, Hamas attack on Israel and the surge of pro-Israel vigils and rallies that followed. Soliman, an Egyptian national, entered the U.S. on a B2 tourist visa in August 2022, overstayed and applied for asylum in September 2022. Investigators say he planned the attack for about a year, sought to kill roughly 20 people and was motivated "to kill all Zionist people." After being denied a gun purchase because of his immigration status, he turned to Molotov cocktails.
He initially pleaded not guilty as federal authorities pursued hate-crime and terrorism investigations. The planned guilty plea in state court will not resolve the separate federal case, which remains pending.
The motivations behind Mohamed Sabry Soliman's attack have sparked significant discussion on social media, with users like @MOSSADil emphasizing the premeditated nature of the firebombing, driven by anti-Zionist sentiment. Journalist @OliLondonTV highlighted the violent targeting of elderly demonstrators, noting Soliman's shouts of 'Free Palestine' during the assault, which left several individuals hospitalized. This incident has drawn broader concerns about rising antisemitism in the U.S., with experts like David Oppenheimer attributing the surge to increased tolerance for bigotry across the political spectrum and the amplification of extremist views on social media platforms.
In the context of immigration, Soliman's overstaying of his visa has reignited debates about illegal immigration in the U.S. Economists Alexander Arnon and Tarek Alexander Hassan have pointed to a post-COVID surge in unauthorized immigration driven by labor demand in various sectors. The intersection of these issues—antisemitism, immigration, and political violence—reflects a complex landscape where rising tensions may lead to more targeted acts of violence, as observed in this tragic event.
