Israeli has described as “political theatre” the trial in Turkey of four Israeli military commanders over the deadly storming of a Gaza-bound aid ship.
Hundreds of protesters chanted as the court case began in Istanbul on Tuesday.
Among those being tried in absentia is the former head of the Israeli army.
Nine Turks were killed during the raid by Israeli marines in 2010.
A Turkish state prosecutor has called for multiple life sentences over the officers’ alleged involvement in the killings and the wounding of 50 other people.
Zekeriya Yapıcıoğlu, a lawyer for the family of one of the victims said: “This case is symbolic. It will show that despite the present structure of the United Nations and the international system, even Israelis who see themselves as above the law, cannot act arbitrarily and will be tried.”
But Yigal Palmour, a spokesman for Israel’s foreign ministry said the court case is nothing but a “show trial”.
“How can this be a trial if the so-called accused have not even been notified or informed that they are going to be accused or that there are going to be charges pressed against them, or what nature of the charges even is. One thing is certain, this is a trial taken right out of a Kafka novel”.
The case has heightened already strained relations between the former allies.
Nearly 500 people, who were on board the ship, are due to give evidence.
Bora Bayraktar, euronews’ correspondent in Istanbul told us that: “There was non-stop noise in front of the justice building during the hearing. Hundreds of protesters chanted slogans against Israel, calling for justice”.
