No injuries were reported and no arrests had been made as of Friday morning, police said, adding that the fire had been extinguished.

Police said the blaze began at about 3:40 a.m. local time.“Around 3:40 a.m., a fire was started at the synagogue,” Rotterdam police said in a post on X, noting that the flames burned briefly before being brought under control.

Authorities have appealed for witnesses or anyone with relevant information to come forward as investigators work to determine the circumstances surrounding the incident.

The fire comes days after another synagogue about 200 kilometres away in Belgium was struck by an explosion earlier this week, which authorities described as an antisemitic attack.

That incident caused property damage but no injuries.Separately, in the U.S. state of Michigan, a Lebanon-born American citizen drove a truck into a synagogue and its preschool before being shot dead, according to authorities.

Authorities and community groups have warned of rising risks to Jewish institutions worldwide following U.S. and Israeli airstrikes on Iran and Tehran’s subsequent response.

The Rotterdam investigation is ongoing as police seek to establish the motive and identify those responsible.

-Israeli war with Iran pushed global oil prices above $100 a barrel and intensified military and diplomatic tensions across the Middle East.Iran’s Assembly of Experts, an 88-member clerical body responsible for selecting the supreme leader, said it had voted decisively to appoint Ayatollah Seyyed Mojtaba Hosseini Khamenei as the third leader of the Islamic Republic, according to a statement issued shortly after midnight Tehran time.

Mojtaba Khamenei replaces his father, Ali Khamenei, who was killed in one of the first strikes launched against Iran during the conflict that erupted more than a week ago between Iran and a U.S.-Israeli alliance.The supreme leader holds ultimate authority over Iran’s political system, armed forces and strategic decision-making.

Mojtaba Khamenei, a cleric known to wield influence within Iran’s security establishment and the vast economic networks built during his father’s rule, had long been viewed as a leading contender to succeed the elder Khamenei.The Assembly of Experts said the vote followed deliberations over the succession after the death of the longtime leader.

The appointment signals continuity in Iran’s ideological leadership during a period of escalating military confrontation.Iran’s armed forces leadership pledged allegiance to the new supreme leader following the announcement, reinforcing the authority of the office at a moment when the country is engaged in active conflict with regional and Western adversaries.The war has already produced significant military and economic repercussions. Oil markets reacted sharply, with U.S. crude futures surging more than 20% amid fears the conflict could disrupt energy flows from the Middle East, a region that accounts for a substantial share of global oil supply.

U.S. President Donald Trump had earlier suggested Washington should influence the selection of Iran’s next leader, remarks that risked inflaming tensions further.“If he doesn’t get approval from us, he’s not going to last long,” Trump told ABC News on Sunday when asked about the succession.

After Mojtaba Khamenei was named, Trump declined to comment directly on the appointment in an interview with the Times of Israel, saying only, “We’ll see what happens.”Trump also told the newspaper that any decision to end the war would be made jointly with Israeli Prime Minister Benjamin Netanyahu.Israel had previously warned it could target whoever emerged as Iran’s next supreme leader, underscoring the stakes surrounding the succession during wartime.

The military confrontation has continued to escalate across the region. Israel struck major fuel storage facilities near Tehran as part of its campaign against Iranian infrastructure.Iran has also launched retaliatory strikes against U.S. facilities in the Middle East.The U.S. military said a seventh American service member had died from wounds sustained during Iran’s initial counter-attack a week ago. The announcement came a day after Trump oversaw the return to the United States of the remains of six other U.S. personnel killed in the same attack.Amid mounting security concerns, Washington on Sunday ordered the departure of non-emergency employees from its embassy in Saudi Arabia, the latest drawdown of American diplomatic staff in the region as the conflict deepens.
