WASHINGTON, D.C. - U.S. Secretary of State Hillary Clinton has said the U.S. strongly supported the UN call for an urgent, impartial, transparent and reliable investigation into the deadly Israeli raid on the Gaza-bound aid flotilla.

Clinton told reporters Tuesday in the Department of State that they also would support Israel to conduct an investigation that would carry such qualities.

She said they were open to different suggestions including an investigation with international participation, adding that they would share their views with the Israeli administration and international partners in the days to come.

Clinton said both Turkey and Israel were good friends of the U.S. and they were working with both countries to find ways to deal with the consequences of "this tragic event".

Clinton said they supported the Security Council statement that condemned the acts that caused this tragedy.

Emphasizing that the situation in Gaza was unsustainable and unacceptable, Clinton said that Gaza's access to humanitarian aid and reconstruction materials ought to be ensured. She said however that the security of Israel was also important.

Clinton said they would continue to work with UN and independent international organizations and Israeli and Palestinian administrations to ensure Gaza's access to humanitarian aid including reconstruction materials.
