The victims were found after firefighters extinguished a vehicle fire at a petrol station near the village of Amendolara in Calabria, a major agricultural region that employs large numbers of migrant laborers.

Investigators are treating the case as a homicide after surveillance footage reportedly showed two individuals blocking the vehicle’s doors from the outside before pouring a liquid into the van and setting it alight. The footage then showed flames engulfing the vehicle as the suspects fled the scene, according to Corriere della Sera newspaper.

Firefighters discovered the four bodies inside the minivan after bringing the blaze under control. Authorities have not publicly released the identities of the victims.

“This is definitely murder, we just have to work out the details,” local police chief Antonio Borelli was quoted as saying by Corriere della Sera.

The arrests come amid broader concerns over tensions within migrant communities working in Calabria’s agricultural sector. According to the newspaper, the area has recorded 14 arson incidents involving cars and minivans used by Pakistani migrants in recent months.

Investigators are examining whether the killings were linked to disputes over access to seasonal farm work, residency documentation, or accommodation, issues that have periodically generated friction among migrant workers in the region.

Calabria’s agricultural industry relies heavily on foreign labor, with migrant workers often employed in seasonal harvesting and farm-related activities across the region’s extensive farming districts.

Authorities have not disclosed additional details regarding the motive for the attack as the investigation continues.

The London Fire Brigade said it deployed six fire engines and about 40 firefighters to the scene near a synagogue in Golders Green, where multiple cylinders inside the vehicles exploded, shattering windows in an adjacent apartment block.

The fire was brought under control by 0306 GMT.The ambulances were operated by Hatzola, a not-for-profit volunteer emergency response group serving the Jewish community.

Starmer called the incident “deeply shocking” and said antisemitism had no place in British society. Writing on X, he said his thoughts were with the Jewish community affected by the attack.

London Mayor Sadiq Khan also condemned the incident and said police patrols in the area would be increased.

The Metropolitan Police said officers remained at the scene and that the case was being treated as an antisemitic hate crime.

The SITE Intelligence Group reported that an Iran-aligned militant collective calling itself the Islamic Movement of the People of the Right Hand had claimed responsibility for the attack.

The group has allegedly been linked to similar arson incidents targeting Jewish sites in Belgium, Greece and the Netherlands, according to the same source.Mark Gardner, chief executive of the Community Security Trust, said the incident bore “an obvious parallel” to recent anti-Jewish arson attacks in cities including Liege, Rotterdam and Amsterdam.

Attacks on Jewish individuals and institutions have risen globally since the October 2023 Hamas attacks in Israel and the subsequent war in Gaza. British authorities have also reported a sustained increase in antisemitic incidents during this period.

Starmer said earlier this month that the government would work with both Muslim and Jewish organizations to ensure adequate security at sensitive locations, warning that broader regional conflicts, including tensions involving Iran, risk exacerbating domestic divisions.

Britain has seen several serious incidents in recent years, including a 2025 attack in Manchester in which two Jewish worshippers were killed during Yom Kippur.
