A ministry statement said Israel's commission declaration did not in any way meet Turkey's clear demand or international community's expectations, which were expressed in the Presidential Statement of the United Nations (UN) Security Council.
Israel earlier declared that it would establish a commission, composed of Israeli citizens and two foreign observers, in order to investigate the Israeli raid against the "Freedom Flotilla".
"Israel does not have the authority to assign a national commission to investigate a crime perpetrated in international waters," the statement said.
In the statement, the ministry said an inquiry to be conducted by such a committee could not be impartial, fair, transparent and credible.
The ministry said Turkey had indeed already agreed to the proposal by the UN Secretary General to establish an international commission to be composed of one Turkish, one Israeli and three international experts.
" We strongly condemn Israel's disregard of this proposal to date. We expect that the international community, above all, the USA that lost a citizen of her own, support this constructive proposal by the UN Secretary General and take action in that direction without delay," the ministry also said.
Nine people, including eight Turkish and one U.S. citizen of Turkish descent, died when Israeli forces raided a Gaza-bound aid flotilla on May 31. Around 30 people were wounded in the attack.
