Many MPs have taken to Twitter to pay tribute to those who witnessed the attack in Woolwich yesterday and tried to help and sent their thoughts to the family of the man who was killed:
Not a day for humour. Time now to pray for the family of the man murdered in Woolwich & salute the bravery of those who went to help him.
Following the barbaric murder in #Wolwich Our community must stand together against all extremists that seek to divide us
Reading accounts of the brave women in Woolwich tonight shielding the body of the soldier (RIP) & quietly tackling the murderers. Heroines.
