Federal prosecutors in New York City have brought charges against a man already held in Germany in the slaying of two U.S. airmen.

A criminal complaint filed Tuesday charges Arid Uka (AH'-reed OO'-kah) with murder, attempted murder and firearms counts.

The complaint alleges Uka approached a bus on March 2 at a Frankfort airport and asked in English if it was carrying Americans. It says he then fatally shot 25-year-old Senior Airman Nicholas J. Alden of South Carolina and 21-year-old Airman 1st Class Zachary R. Cuddeback of Virginia. He also wounded two others.

The 21-year-old Kosovo Albanian was quickly captured and is facing murder and attempted murder charges in Germany. Authorities there have said he told police he wanted to kill Americans "as revenge for the American mission in Afghanistan."
