German police have launched a major investigation after two US servicemen were shot dead on an army bus outside Frankfurt airport.
A 21-year-old Kosovan man has been arrested following the incident on Wednesday, which also saw two others troops seriously wounded.
President Obama described the shootings as outrageous, while German chancellor Angela Merkel also condemned the attack.
“I offer my condolences to the families of the American soldiers. It’s a terrible thing that’s happened. Germany will do its utmost to try and quickly get to the bottom of this,’‘ the German leader declared.
Kosovo’s government announced it believed it had evidence to identify the suspected gunmen.
Security at the hub has also been stepped up, despite Germany already being on a high level of alert with fear of an imminent terrorist strike.
For the moment, the motive for the shooting remains unclear, but it is thought a possible argument may have broken out on the bus before the killer opened fire.
