Six people are confirmed killed, with at least another forty eight injured.
My neighbour's daughter was in a restaurant a few hundred yards away when the attacks took place; when she finally got home she told her father there was absolute pandemonium, and lots of armed police and ambulances everywhere.
Seven people now confirmed dead, and some of the 48 injured are 'critical'
The attackers were wearing fake bomb belts, which is initially puzzling but when you think about it, they probably wanted to draw attention to themselves and look sufficiently dangerous for armed police to shoot them dead. It's as if being killed themselves was part of the plan.
"I don't understand why ownership is so unrestricted".
I can see what you mean, but think about how would you possibly restrict ownership - what criteria would you use? Drones aren't weapons; if you impose restrictions on owning anything that might be used to kill or maim, you would be controlling society to an unacceptable level.
I'm all for some form of registration scheme for drones, but that would be so easy to fake it would be meaningless.
