At least four people have been injured in a knife attack in a railway station near Munich in south Germany, early on Tuesday.
The attack happened at around 5 am local time at Grafing station, some 25 kms from Munich. A news paper delivery van driver was among those knifed.
One of the critically injured later died in the hospital.
Bavarian radio said all the injured have life threatening injuries.
Local police are looking into claims that the attacker shouted “Allahu Akbar” (God is Great) before stabbing the passengers.
A German news outlet said the suspect was young, possibly with an immigrant background, but the police had no record of him.
Trains were running, but were behind schedule.
Authorities have stepped up security across Germany, following Tuesday’s attack.
While neighbours France and Belgium have experienced major attacks, Germany which plays a supporting role in the fight against Islamic State, has not suffered any major terror strike.
