U.N. chief Ban Ki-Moon announced on Monday the launch of a four-person international panel to probe deadly Israeli attack into a Gaza-bound Turkish aid flotilla.
The announcement comes months after Turkey repeatedly has said, it would only accept an international probe, rejecting Israeli internal panels.
The 31 May attack in which Israel raided a six-ship convoy in international waters that was carrying humanitarian goods and activists and heading for Gaza killed nine Turkish civilians, wounding at least 30 others.
In a statement, Ban said the panel would be led by former New Zealand prime minister Geoffrey Palmer and outgoing Colombian President Alvaro Uribe and would also have one Israeli and one Turkish member.
There was widespread public outrage in Turkey over Israel's murders of citizens.
Meanwhile, Israel decided on Monday "to cooperate" with the investigation, officials said.
Senior members of Prime Minister Benjamin Netanyahu's cabinet voted "to allow the panel access to material gathered" by two Israeli committees conducting internal probes, Reuters news agency reported.
But it is not immediately clear if Israel would allow full access to UN panel members, such as questioning Israeli commandos involved in the flotilla attack.
Yet, following the cabinet decision, for the first time, Israel has agreed to cooperate in a UN investigation related to an incident involving Israeli soldiers. For the first time again, Israel will become a part of a UN investigation committee regarding its activities.
He said the panel would begin its work August 10 and would submit its first progress report by mid-September.
Turkey has withdrawn its ambassador, cancelled joint military exercises, and called for Israel to end its blockade of 1.5 million Palestinians.
