According to local reports, the bomb contained almost no explosive material, caused no damage to anything, exploded at 01:40 and was placed 30m from the embassy. The people arrested were 17-21 years old. Sounds more like barely adult assholes blowing up what was effectively a firecracker in an act of self-perceived protest. It is definitely not a terrorist attack.

I think a lot of people hear Red Light District and visualise a neighborhood of a few blocks… It’s literally a 500m stretch of a canal and a a few tiny alleys, mostly on one side. It is very close to the main train station (literally across the street from one end of the station, but, to be clear to any Americans, the station is mall-sized), but that’s the whole thing. It’s filled with curious tourists so much that you can’t really walk because of the foot traffic. It’s… underwhelming. It’s the kind of place you go to, spend half an hour walking a block back and forth because of the traffic, say “that’s it?” and go do something more interesting.
