Nothing unexpected. Outside London you can feel a silent but still palpable dislike towards muslims since ages almost everywhere in the UK. After the recent islamist terrorist attacks I'm not surprised if someone tried to retaliate. BTW this was a badly organized, amateurish attempt by some not very smart guy. We'll see if this will turn a tendency or just one of a few isolated cases.
Did islamist attacks ended up in just a few isolated incidents?

Who comes to the country with the sword will die by the sword, so was said in the Testament. It is just matter of time before London and Paris become like Lebanon - used to be 84% christian before muslims from all over migrated to it and started replacing natives.
Omg shut the fuck up
We're bringing bombers, soldiers, tanks, drones and much worse in their countries.
They brought what? 3 bombs and 2 AK-47 in ours?
Stop trying to hide yourself in your nasty little biggoted ass. You attacked them first, you killed thousands of children, women and men perfectly innocent. And now you're crying like a little bitch because they come and kill 50 kids?
Damn if I were them I'd put your country on its knees and fuck you like you really deserve it.
