Home Secretary Amber Rudd said:
This was an horrific attack in the heart of our capital city, targeted at people enjoying their evening with friends and family. My thoughts are with the victims and all those affected by this incident.
As ever, in difficult and traumatic circumstances, I am extremely proud of and thankful to our police and emergency services who responded so swiftly and those who will work tirelessly as the investigation into this appalling act continues.
