Turkey has downgraded diplomatic ties with Israel and frozen military cooperation ahead of a long-awaited United Nations report on Israel’s deadly attack on a Gaza-bound ship in 2010. According to leaked excerpts, the report accuses Israel of “excessive and unreasonable” force in its attack on the ship, Mavi Marmara, which killed nine people. The report says Israel should issue a statement of regret and compensate the families of the dead as well as wounded passengers. But the report also chides passengers aboard the Marmara and the other flotilla ships for what it calls a “reckless” attempt to breach Israel’s blockade of the Gaza Strip. And in a development with broader implications, the U.N. report also concludes that the Israeli blockade of the Gaza Strip is legal under international law. The U.N. investigation was overseen by Geoffrey Palmer, a former prime minister of New Zealand. Turkey says it will expel the Israeli ambassador and downgrade diplomatic ties to their lowest level until Israel drops its refusal to apologize for the raid and provides compensation.
