A knife attacker slashed a man at an east London metro station, reportedly screaming "this is for Syria", in what police described as a terrorist incident, prompting the government to urge Britons on Sunday not to be intimidated by the attack.
Police said initial reports indicated the man, believed to be aged 29, had also threatened other bystanders. One 56-year-old man suffered serious but not life-threatening injuries. Two other people had minor injuries, police said. "We are treating this as a terrorist incident," Richard Walton, who leads the Counter Terrorism Command at London's Metropolitan Police, said in a statement.
An eyewitness quoted by The Guardian and other British newspapers said the attacker appeared to claim that he was retaliating for Western air strikes on Islamist militants in Syria. Islamic State said on Saturday that the married couple who killed 14 people in a mass shooting in California were followers of the militant group.
