It claimed that there was "clear evidence to support prosecutions." Prime Minister Binyamin Netanyahu called the report "biased and distorted."A government spokesperson reiterated that the flotilla is already being investigated by Israel with the involvement on international observers, as well as the UN investigation. Speaking of a potential ICC investigation, he said that "further investigations are redundant and unnecessary, and will contribute to further alienation between otherwise friendly countries," according to the Guardian report.The ICC only has jurisdiction in countries that are party to the Rome statute, which established the court. Israel is not party to the statute, but the Turkish lawyers said that the fact that the Mavi Marmara was flying the flag of the Comoros Islands and Turkey's involvement with the flotilla give the court sufficient jurisdiction, The Guardian reported.According to the Guardian report, the letter from the Turkish lawyers said, "We are of the view that the Israeli attack on the Gaza flotilla involves crimes which fall unambiguously within the jurisdiction of the court."
