Last Wednesday the 22nd March 2017 four people died in Westminster attack.
A policeman has been stabbed and his apparent attacker shot by officers at the Houses of Parliament.
Up to one dozen people were also injured after a car mowed down people on Westminster Bridge.
However, we all need to stay united and strong and not let fear command our lives. #PrayForLondon
