Police investigate fire attack on Dutch synagogue

Dutch police have opened an investigation into an arson attack on a synagogue in Rotterdam, in the latest incident of suspected anti-Semitic violence since the start of the US-Israeli war on Iran.

No one was injured as a result of the overnight fire, and no arrests had been made, the city's police said on Friday.

Another synagogue, 200km away in neighbouring Belgium, was hit by an explosion on Monday in what authorities said was an anti-Semitic attack. That attack caused damage but no injuries.

In Michigan in the US, a Lebanon-born US citizen crashed his truck into a synagogue and its preschool and was shot dead.

Concerns about possible attacks against Jewish communities around the world have risen following US and Israeli air strikes on Iran and a subsequent response by Iran.
