MPs have backed calls for an inquiry into the Israeli attack on an aid convoy to Gaza.
John Hemming (Lib Dem Yardley) said the raid, which led to the deaths of at least nine civilians, should be seen as an act of “piracy”.
He called for a criminal inquiry into the incident. The MP said attacks on Israeli civilians by Palestinian groups should also be investigated.
Fellow Birmingham MP Khalid Mahmood (Lab Perry Barr) called for calm, but said the raid could lead to “revenge attacks” across the world.
The United Nations Security Council has called for a “prompt, impartial, credible and transparent” investigation into the assault on a ship carrying aid to the Gaza strip, which is home to 1.5 million people and has been blockaded by Israel and Egypt since 2007.
They claim the blockade is needed to prevent rockets and other weapons being smuggled into Gaza.
Mr Hemming said: “The attack on the aid convoy to Gaza has to be seen as a job for the international criminal court to investigate as an act of piracy.
“It does, however, raise the question as to how it becomes possible to move towards peace in the Middle East without greater intervention from international bodies.
“Somehow there needs to be international peace keeping action to keep the sides to the conflict from attacking each other.
“At the same time bodies such as the International Criminal Court need to get involved in investigating and prosecuting what are war crimes. That includes bombing the Israelis with rockets - which was some time ago.”
Mr Mahmood said: “This outrageous attack on individuals delivering humanitarian aid should be condemned by all of those who respect life and international law.
“The increasingly irresponsible actions of the Israeli state not only result in the death of Palestinian civilians and those who support their just demand for a homeland, it also provokes revenge attacks against Jews throughout the world and against the innocent citizens of those states seen to be uncritically supporting Israel.”
MEP Liz Lynne (Lib Dem West Midlands) said: “It appears this was an appalling attack by heavily armed soldiers on a humanitarian mission in international waters, which must be condemned utterly.
“It’s vital we have a full and independent inquiry into this incident as a matter of urgency.”
Deputy Prime Minister Nick Clegg called on Israel to lift its “unjustifiable and untenable” blockade.
“Whilst, of course, Israel has every right to defend itself and its citizens from any attack, it must now move towards lifting the blockade in Gaza as soon as possible,” he said.
The Foreign Office has confirmed that one Briton was among more than 30 people injured and had received medical treatment.
