The International Criminal Court (ICC) is expected to officially declare that Israel is guilty of "war crimes" on Thursday for the attack on a Turkish aid ship bound for Gaza in 2010, Bulent Yildirim, president of Turkish NGO IHH Humanitarian Relief Foundation, said on Wednesday. Israeli commandos killed eight Turkish nationals and an American of Turkish origin in a raid on aid flotilla "Mavi Marmara", which was carrying humanitarian aid and construction materials for Palestinians in the Gaza Strip.
