Two men suspected of being connected with the arson attack on four ambulances outside the Machzike Hadath synagogue in London were arrested on Wednesday. Counterterrorism officials in the United Kingdom apprehended two men, ages 45 and 47, “on suspicion of arson with intent to endanger life.”

The attack occurred early Monday morning in London’s largest Jewish community in Golders Green at a Jewish community rescue service. The attack was being investigated as an “antisemitic hate crime.” The two men remained in police custody by the London Metropolitan Police Department. Authorities searched two addresses believed to be where each man was staying.
