The U.S. will launch an investigation on the death of an American citizen in an Israeli raid on a Turkish aid ship bound for Gaza, the U.S. State Department said on Thursday, Xinhua reported.
"We will look into the circumstances of the death of an American citizen, as we would do anywhere in the world at all times," State Department spokesman Philip Crowley said.
But Crowley did not specify which government agency will conduct the investigation.
Israeli commandos on Monday launched raid on an international aid flotilla bound for Gaza, killing nine and injuring dozens.
Eight of the nine dead were Turkish citizens and the other was a 19-year-old American citizen from the state of New York, with Turkish origin. Israel's attack has since caused international outcry.
