Rather slim on details so far, but London police have arrested an armed man outside of the Houses of Parliament on Thursday. The man reportedly had a "backpack of knives."
The BBC is reporting that nobody was injured.

It is unknown now if the man was connected with any sort of terrorist group. An attack outside of Parliament last month killed four.
