Authorities say the suspect in the car-ramming attack in Munich that injured 39 people appears to have had an Islamic extremist motive, but there’s no evidence that he was involved with any radical network.

Police arrested an Afghan asylum seeker at the scene of what German leaders labelled a car ramming "attack" Thursday that wounded 30 people, some seriously, in the southern city of Munich.

A car drove into a union demonstration in central Munich injuring at least 28 people including children, authorities said. Bavarian governor Markus Soder said the incident on Thursday was “suspected to be an attack”.
