British Prime Minister Theresa May is calling for the country to unite after Saturday's deadly terrorist attack in London.

"We cannot and must not pretend that things can continue as they are. Things need to change," May said in a statement Sunday.
May said the recent attacks in England are bound together "by the single, evil ideology of Islamist extremism that preaches hatred, sows division and promotes sectarianism."
Defeating that ideology, she said, is "one of the great challenges of our time."
May added that the ideology cannot be given the "safe space it needs to breed."
May also said Britain's counterterrorism strategy must be reviewed due to "what we are learning about the changing threat."
"Since the emergence of the threat from Islamist-inspired terrorism, our country has made significant progress in disrupting plots and protecting the public," she said.
"But it is time to say enough is enough. Everybody needs to go about their lives as they normally would. Our society should continue to function in accordance with our values. But when it comes to taking on extremism and terrorism, things need to change."
The country's response to the violence, she said, needs to be to unite.
"We must come together, we must pull together, and united we will take on and defeat our enemies," she said.
May's comments come after an attack Saturday on and near the London Bridge that killed at least seven people and wounded dozens more.
