U.S. Defense Secretary Leon Panetta has asked the U.S. Marine Corps to look again at an investigation, which concluded that Marine snipers who posed with a logo resembling a Nazi symbol in Afghanistan should not be disciplined.
Pentagon press secretary George Little said Panetta asked the Marine Corps on February 10 to look into it "and to take appropriate action."
Little added that the use of racist and anti-Semitic symbols was unacceptable among U.S. service members.
The Marine Corps has said it does not plan to discipline the troops.
The soldiers posed for a photo in 2010 in front of a flag with a logo resembling that of the Nazi SS, since it concluded there was no malicious intent.
A leading Jewish organization in the U.S. has demanded President Barack Obama order a full investigation.
