A suspected Muslim terrorist who killed two U.S. airmen in Germany was charged in absentia this week in a Manhattan U.S. federal courtroom. Arid Uka, 21, was charged Tuesday with first-degree murder.

The murderer allegedly yelled “Allah Ahkbar" (Allah is Great) during the shooting spree March 2 at Frankfurt International Airport, an eyewitness said. Uka, a devout Muslim, was an employee at the airport. 

Airman 1st Class Zachary Cuddeback and senior Airman Nicholas Alden were both shot in the head at close range. They died instantly. Two USAF personnel were wounded as well. Then Uka's gun jammed, and German security personnel immediately moved in and took him into custody, where he remains.

According to the court documents Uka, born in Germany of Kosovo ancestry, became a radical Muslim after watching related videos on the Internet. He confessed to German authorities that he opened fire at American Air Force personnel in retaliation for the U.S. invasion of Afghanistan.

A spokeswoman at the U.S. Attorney's Office in Manhattan declined to tell the New York Post when Uka would be in New York to face trial.
