A military report by Israel has concluded that its stopping of an aid flotilla bound for Gaza was undermined by mistakes at a senior level.
The flotilla was trying to break Israel's blockade of the Gaza Strip when it was intercepted by commandos in international waters on 31 May. Nine Turks were killed. The incident provoked an international outcry.
The report into the operation also criticises intelligence gathering and forward planning.
It said the commanders also relied too heavily on one single plan.
The BBC reports this is the first of two inquiries and looks at the military aspects of the operation.
Political and legal ramifications will be examined in another inquiry.
Israel has resisted calls for a UN inquiry into the raid, saying it would be biased.
