Mr Perrett said the convoy carrying 10,000 tonnes of humanitarian aid, aimed at breaking the Israeli siege of Gaza.

"Latest reports indicate that this unjustifiable attack, which took place in international waters, has left at least 10 people dead and 30 injured.

"One Australian is wounded and two Australians journalists detained."

"I join the Foreign Affairs Minister Stephen Smith and the international community in condemning the terrible and shocking violence."

Mr Perrett said he supported international condemnation of the Israeli attack, and reiterate the Minister's calls for a full ‘credible, transparent investigation' into the bloodshed.

"I am personally appalled by Israel's attempt to justify and defend what is an indefensible attack on the humanitarian aid convoy, which included parliamentarians from across the world.

"Israel's narrative can only be described as being bereft of a sense of reality towards its own obligations and responsibilities in upholding international law and the principles of democracy.

"Our thoughts go out to those on board the Freedom Flotilla humanitarian aid convoy, who were subjected to this aggression.

"I also sympathise with those people in Israel who so desperately want peace within the framework of international law. It is clear that their government has once again let them down.

"The international community must now hold Israel to account, not only on this latest incident, but on its continued siege of war-ravaged Gaza - and stranglehold of the West Bank and East Jerusalem - and recognise that its ongoing actions are an inherent obstacle to the peace process."
