No injuries were reported in what Amsterdam’s Mayor Femke Halsema described as a “deliberate attack.” It follows an arson attack on a synagogue in Rotterdam a day earlier.

A Jewish school in Amsterdam was hit by an explosion early on Saturday in what the city’s mayor called “a deliberate attack against the Jewish community.”
The explosion on Saturday is the latest in a spate of suspected attacks against Jewish institutions in recent weeks. Many of these incidents coincided with the US-Israeli war against Iran.
What we know so far
Police said investigators determined the two suspects arrived on a motor scooter. One of them placed an object against the wall before running back to the scooter, with the device detonating as they sped away.
No injuries were reported and damage was limited. Security at synagogues and Jewish institutions across the Netherlands has since been tightened following the incident.
Mayor Femke Halsema condemned a “cowardly act of aggression against the Jewish community.”
“Jewish people in Amsterdam are increasingly confronted with antisemitism. This is unacceptable,” she said.
“A school must be a place where children can learn safely. Amsterdam must be a place where Jews can live safely.”
