Mossad supplied Kurdish militias with weapons captured from Hamas and Hezbollah for an anti-Iran operation, Ynet reported on June 4.
The Israeli outlet said the weapons came from Israeli military operations in Gaza and Lebanon. Ynet also reported that the US Central Intelligence Agency took part in the initiative.
The plan aimed to use Kurdish forces in Iraq and Iran to pressure Tehran during the wider conflict. Ynet said the support included money, vehicles and military equipment.
US President Donald Trump later cancelled the plan after Turkish President Recep Tayyip Erdoğan objected.
Türkiye feared the use of Kurdish fighters could widen the war and inflame ethnic tensions, Turkish newspaper Daily Sabah reported in March.
Daily Sabah said Ankara warned Kurdish political figures, including members of the Barzani and Talabani families, against joining the effort.

The Turkish report also said about 500 operatives moved from Iraq to Iran before Turkish intervention disrupted the plan.
The claims have not received public confirmation from Mossad, the CIA, Türkiye or the White House.
