Terror Attack in Barcelona (Spain)

[swl]

I currently live 100 meters away from that place, in one of the streets perpendicular to la Rambla and walk the whole Rambla every day on my way to and from work. I am on holidays so not there right now.
La Rambla is very crowded with tourists and most victim will be foreigners (locals tend to avoid that place).

There are always armed policemen on the street but there is not much they can do against this type of attack.

Police is linking this attack with the explosion of a house near Barcelona that blew up the night before. They say there were around 20 gas bottles in the house when it exploded.
Rumors are that the initial plan to use the rented vans as car bombs but it failed when the house exploded, so the remaining terrorists changed the plan.

With the people killed/injured in the house explosion + the 5 killed during the night + van driver (18 years old boy still on the run) we are talking of 10 people at least.
