Frankfurt, Germany (CNN) -- The man suspected of shooting and killing two U.S. Air Force servicemen in Germany was seeking revenge because of U.S. military operations in Afghanistan, according to a warrant issued on Friday for the suspect. The suspect, Arid Uka, is a recently radicalized Muslim who seems to have been influenced by local radical Islamist websites, according to German authorities. Prosecutors say Uka shot and killed two U.S. servicemen and wounded two others in the attack Wednesday on a U.S. military bus at Frankfurt Airport. The arrest warrant for Uka lists two accusations of murder, three allegations of attempted murder and two accusations of causing severe bodily harm.
