Eleven Australians detained by Israeli forces while attempting to deliver aid to Gaza have submitted evidence to the International Criminal Court alleging abuse, torture and other violations during their detention.

The allegations have not yet been tested in court. The Israel Defense Forces (IDF) has rejected claims that flotilla participants were mistreated while in custody.

The Global Sumud Flotilla called for independent international investigations, arms embargoes and reparations for alleged victims.

Australians detained by Israeli forces while trying to deliver humanitarian aid to Gaza have taken evidence of alleged abuse and mistreatment to the International Criminal Court (ICC).

The 11 Australians were among an international flotilla of more than 400 people who were intercepted and detained on May 18 while trying to break Israel's naval blockade on the war-torn Gaza Strip to deliver food, medicine and baby formula.

Australians involved in the mission were Anny Mokotow, Bianca Webb-Pullman, Neve O'Connor, Violet Coco, Gemma O'Toole, Sam Woripa Watson, Zack Schofield, Helen O'Sullivan, Juliet Lamont, Isla Lamont and Surya McEwan.

In a statement issued on Friday, the Global Sumud Flotilla said activists had lodged a submission to the ICC, alleging war crimes, crimes against humanity, torture and other violations of international law.

Most of the 11 Australian activists on the Gaza-bound Global Sumud Flotilla have returned home after being detained by Israel.

"The submission presented to the ICC focuses heavily on the [alleged] severe, widespread abuses against civilians, including journalists, medics and human rights defenders as part of a coordinated campaign of violence."

The Global Sumud Flotilla called for independent investigations, arms embargoes and reparations for alleged victims.

The Israel Defense Forces (IDF) has rejected claims that flotilla participants were mistreated while in custody.

"IDF orders require respectful and appropriate treatment of flotilla participants on the intercepted vessels, and there are clear and established procedures in this regard," it said in a statement.

"No specific incidents of deviation from these binding procedures are known within the IDF. Any concrete complaints submitted to the IDF on the matter will be examined thoroughly."
