spirit. boris johnson the prime minister was up on that bridge behind me just a very short time ago. this is what he said about yesterday's events. >> we saw in four minutes the terrorist, the assailant was tackled within five minutes. incredible response by police. also want to pay tribute, again, as i think the whole country is to the sheer bravery of those members of the public who went to deal with him spontaneously, putting their own lives at risk. >> reporter: so the queen elizabeth released a statement from buckingham palace expressing sadness of having heard the attacks but offering her thanks to police and emergency services who responded and, of course, she describes the brave individuals who put their own safety at risk to help and protect others. >> amazing stuff, thank you very much for that.
