Turkish report claimed Monday that the US Congress canceled a deal to supply Ankara with 10 Predator drones because the Turkish government had blown the cover of several Iranian intelligence assets who were working with Israel.

According to the daily Taraf, the head of Turkish intelligence, Hakan Fidan, exposed the 10 Iranians – who had secretly been meeting with Mossad handlers – to the Islamic Republic more than three years ago, after the Israeli takeover of the Gaza-bound Mavi Marmara. Nine Turkish citizens were killed in the operation, which led to Ankara’s all but freezing its relations with Israel.

The US drones were to be delivered to Turkey in mid-2012, but according to the report, Congress canceled the deal because of the growing cooperation between the Turkish and Iranian intelligence services.
