Driver in German van attack had history of run-ins with police

It was not clear whether the incident was an attack

The daily Sueddeutsche Zeitung said police had found an 18-page missive in his Pirna home in which he wrote of his anguish due to serious problems with his parents, "repeated nervous breakdowns" and "explosions of aggression" as well as a botched medical operation.

Herbert Reul, the interior minister of North Rhine-Westphalia state, also said that investigation on the driver, who was a German citizen, has so far yielded no proof of any possible "Islamist background".

Armin Laschet, the governor of North Rhine-Westphalia state, where Muenster is located, visited the crash scene on Sunday.

Prosecutors said the suspect had been known to them, but only for minor infractions. One of the suspects apparently held multiple weapons that were "especially sharpened for this objective".

Police investigators were still trying to learn the man's motive.

Bode also said police had found a suspicious object inside the van and were investigating it.

Kenyan Erick Kiptanui clocked a course record of 58 minutes, 42 seconds, equalling the fastest time in the world this year, the race's organisers said on their website.

"Unbelievable that something like this could happen in Muenster".

Police in the western German city of Muenster say a vehicle has crashed into a crowd there, killing several people and injuring others.

Amri's attack in Berlin in 2016 prompted German lawmakers to call for tougher security measures.

Elke Adomeit told reporters the Muenster authorities had three criminal proceedings against him while there was a further charge against him with the Ansbach prosecutor.

"Everything conceivable is being done to investigate the crime and to support the victims and their relatives", Merkel said in a statement.

French President Emmanuel Macron tweeted: "All my thoughts are with the victims of the attack in Muenster".

The White House issued a statement following the incident saying US President Donald Trump's "thoughts and prayers" were with the families of those killed. In the months prior to the Berlin assault, Germany suffered a number of small-scale Islamist militant attacks, which some linked to Merkel's decision in 2015 to open the country's borders to an influx of migrants, many of them refugees from conflicts in the Middle East.

Saturday's crash occurred on the one-year anniversary of a similar attack in Stockholm, Sweden, when a stolen beer truck struck pedestrians, killing five people.

Der Spiegel reported that police were investigating a similar incident that occurred in the eastern German city of Cottbus on Friday evening, when a man drove his vehicle into a group of people, injuring two, before fleeing.
