Israel is not co-operating with the UN Human Rights Council's probe of May's deadly raid on a Gaza-bound aid flotilla, a UN official said today.

Juan Carlos Monge said the fact-finding mission is speaking to witnesses and government officials in Turkey and Jordan. But Mr Monge said Israel has not granted the team an invitation.

Israel's UN mission said today it was not commenting on the investigation.

Israeli commandos killed nine pro-Palestinian activists trying to break the Jewish state's blockade of Gaza. Israel says the soldiers acted in self-defence.

A report will be presented to the council September 27.

Another UN panel under New Zealand's ex-prime minister Geoffrey Palmer and Colombia's ex-president Alvaro Uribe is also examining the incident.
