the Turkish government did not prevent the attempt by the Marmara to violate the naval blockade - Benjamin Netanyahu
“It appears that [Turkey] did not see in the prospect of a clash between Turkish activists and Israel something that clashed with its interests.”
Mr Netanyahu told the panel, headed by retired Israeli Supreme Court justice Jacob Turkel, and overseen by former Irish First Minister Lord Trimble, that Israel had operated according to international law.
He said Israel had been forced to intervene over the flotilla to prevent weapons reaching Hamas, the militant group which has controlled the Gaza Strip since 2007.
"As prime minister I can't ignore Hamas as a threat to Israel's existence."
Mr Netanyahu has also agreed to take part in the United Nations inquiry , which begins work on August 10.
