Theresa May speaking to Parliament right now. Just confirmed the attacker was, they believe, working alone. They know the identity of the attacker. He is British born. He was historically (not an active case) investigated by MI5 for his Islamist views. They will announce his name in time (I think this is sensible)
She listed the nationalities of those injured on the bridge. There were citizens from Ireland, America, France, Germany, Poland, Romania, South Korea and I've probably forgotten others.
Truly the height of cowardice, attacking these poor tourists. Typical of Islamist terrorists
