British Prime Minister Theresa May on Sunday responded to the country’s fight against Islamic extremism, calling for tougher measures to fight terrorists after attackers killed seven people and injured nearly 50 in vehicle and stabbing assaults in a busy area of London Saturday night. The attack, the third this year and coming days before a nationwide vote in Britain, ended when police shot and killed three attackers at the scene of the carnage at London Bridge and Borough Market. The prime minister delivered a stark assessment of the situation, adding: “It is time to say: Enough is enough.”
