Turkey blew Israeli cover for Iranian spy ring

Amazing story from David Ignatius in WaPo:

The Turkish-Israeli relationship became so poisonous early last year that the Turkish government of Prime Minister Recep Tayyip Erdogan is said to have disclosed to Iranian intelligence the identities of up to 10 Iranians who had been meeting inside Turkey with their Mossad case officers.

Knowledgeable sources describe the Turkish action as a “significant” loss of intelligence and “an effort to slap the Israelis.” The incident, disclosed here for the first time, illustrates the bitter, multi-dimensional spy wars that lie behind the current negotiations between Iran and Western nations over a deal to limit the Iranian nuclear program. A Turkish Embassy spokesman had no comment.

Israeli anger at the deliberate compromise of its agents may help explain why Prime Minister Benjamin Netanyahu became so entrenched in his refusal to apologize to Erdogan about the May 2010 Gaza flotilla incident . ...

Israeli intelligence had apparently run part of its Iranian spy network through Turkey, which has relatively easy movement back and forth across its border with Iran. The Turkish intelligence service, known as the Milli Istihbarat Teskilati, or MIT, conducts aggressive surveillance inside its borders, so it had the resources to monitor Israeli-Iranian covert meetings.

U.S. officials assessed the incident as a problem of misplaced trust, rather than bad tradecraft. They reasoned that the Mossad, after more than 50 years of cooperation with Turkey, never imagined the Turks would “shop” Israeli agents to a hostile power, in the words of one source. But Erdogan presented a unique challenge, as he moved in 2009 to champion the Palestinian cause and, in various ways, steered Ankara away from what had been, in effect, a secret partnership with Jerusalem.

It's not like Turkey loves Iran so much - they exposed the network just for spite.
