Two American soldiers were killed Wednesday at Frankfurt airport when a gunman fired upon a transport bus. The killing occurred at the airport's Terminal 2, which often serves as an interchange for U.S. troops coming and going from the Afghanistan War.
Although details are still emerging, reports claim that two other individuals were also injured.
Police say a 21-year-old Kosovan man was immediately arrested at the airport. Motivation for the killing remains uncertain.
Frankfurt airport is the busiest airport in Germany.

U.S. President Barack Obama has told reporters he is "saddened and outraged" by the attack. "We will spare no effort in learning how this outrageous attack took place," he said, while pointing out U.S. and German authorities are working together. We don't have all the information yet, and you will be fully briefed when we get more information, but this is a stark reminder of the extraordinary sacrifices that our men and women in uniform are making all around the world to keep us safe, and the dangers that they face all around the globe."
Police say the gunman stormed the bus while it was idling and opened fire.
