A muslim or a leftist? At this stage its getting close to a coin toss. Still 60 40 in favour of a muslim I would say. But In the Netherlands, they have been working together since a leftist murdered Pim Fortuyn on behalf of the muslims who he felt the Dutch gay politician had offended.
Probably a Moslem but the way things are going it will be down to a 50-50 choice before the summer is over.
Similar thing happened 4 days ago, also in Amsterdam. Anti-tank missile was fired at a newsroom, I posted it on here before:

Police arrested a member of bike gang Caloh Wagoh MC Main Triad:
https://www.dutchnews.nl/news/2018/06/motorbike-gang-member-arrested-for-anti-tank-missile-attack-on-office/
Likely the 2 attacks are connected, so neither muslim nor leftists are to blame. Gang violence is on the rise in the Netherlands, and of course some gangs are muslim. But Caloh Wagoh was founded by Surinam creoles, who have no connection to islamism.
So what is the motive for attacking news outlets?
Most likely a story they didn’t like.
That sounds like a Middle Eastern gang not a European gang, so the Islam factor is back.
Did the person bail out of the van before it crashed? If not then it is a act of vehicular jihad.
