Man shouted 'Alluah Akbar' as he stabbed passengers

One person has been killed and several injured in a knife attack by a suspected Islamist at a railway station near Munich.

The suspect reportedly shouted "Allahu Akbar" ("God is great") as he started stabbing passers-by in the town of Grafing, to the south-east of the German city.



The attack took place at around 4.50am on Tuesday and the suspected perpetrator, a 27-year-old German man, was arrested shortly afterwards.

A newspaper delivery worker was stabbed in the back during the "indiscriminate" assault, a firefighter told the Merkur newspaper. 

The attack started on an S-Bahn train, where the first victim was injured, before the man stabbed another person inside the station and targeted two cyclists, witnesses told local media.

A spokesperson at the Bavarian state criminal investigation office told The Independent a 50-year-old man was initially in a critical condition but died later in hospital.

Three other men aged 43, 55, and 58 were injured and were undergoing treatment.

A spokesperson for the state prosecutor's office confirmed that the attack was believed to have an "Islamist background" but could not give any further details.

German authorities increased the nationwide terror alert level following November's Paris attacks, increasing security at transport hubs, tourist attractions and major events.

Two railway stations in Munich were evacuated temporarily on New Year's Eve in an alert over an alleged suicide bombing plot by Isis supporters.

More than 800 German jihadists are believed to have joined the so-called Islamic State and other terrorist groups in Iraq and Syria.

Isis has also issued propaganda directed at supporters in the country, including one calling for them to travel to Syria or wage terror attacks at home.
