The U.S. Navy says three members of its elite special forces, known as SEALs, are facing criminal charges in connection with the alleged abuse of detainees in Iraq.

Officials in Washington Saturday said the charges stem from the deaths of two Iraqis while in U.S. custody.

Also, the Pentagon announced Saturday that a U.S. Army soldier has been convicted of the murder of an Iraqi National Guardsman in May, and has been sentenced to 25 years in prison.

These charges come just days after two Army soldiers were charged with murder in connection with the deaths of three other Iraqis.

The expanding investigation into the Iraqi prisoner abuse scandal already has led to criminal charges against four other Navy sailors, as well as at least one dishonorable discharge from the military.
