A pro-Palestinian campaign group on Monday accused Greek shipping firms of transporting oil and military equipment to Israel that helps its war in Gaza, in some cases breaching a Turkish embargo on trade with Israel.
The "No Harbour for Genocide" group called on Greek authorities to investigate and sanction firms running vessels that "turned off their tracking signals and listed false end-destinations before arriving at Israeli ports" to avoid detection.
The group released a report that said between May 2024 and December 2025 at least 57 "covert crude oil shipments" took about 47 million barrels of oil from Turkey to Israel "in violation of Turkey's trade embargo on Israel" since May 2024.
It said some of the oil was being refined into "fuel for the Israeli air force and fuel for military vehicles and tanks".
The report named a number of firms involved in "the shipment of both energy products and military cargo to Israel" that made them "a critical enabler of Israel's genocide and illegal occupation of Palestine, as well as its escalating aggression across the region".
Israel denies that its actions in the Gaza conflict since the October 7, 2023 Hamas attacks amount to genocide.
The Union of Greek Shipowners did not immediately comment on the report, AFP reported.
Greek firms run one of the world's biggest shipping fleets and the industry accounts for about eight percent of Greece's gross domestic product.
