Britain's terror threat level will remain at "severe" after militants killed seven people and injured 48 in London, Prime Minister Theresa May says.
Additional security measures have been put in place, including at several bridges in central London, May said. Three knife-wielding assailants rammed a van into pedestrians on London Bridge and stabbed others nearby.
"JTAC, the independent joint terrorism analysis centre, have confirmed that the national threat level remains at severe, that means that a terrorist attack is highly likely," she told BBC television after a meeting of the government's emergency committee.
"It is now clear that, sadly, victims came from a number of nationalities. This was an attack on London and the United Kingdom, but it was also an attack on the free world."
May says police have identified all the London Bridge attackers and that 11 people remain in custody for possible connections to the attack.
She also defended cuts to police numbers, stating that the Metropolitan Police is "well resourced" and has "very powerful counter-terrorism capabilities".
May was asked whether she regretted as Home Secretary presiding over cuts that have seen 20,000 fewer police officers on the country's streets, in the wake of Saturday night's attack.
She said: "The Commissioner of the Metropolitan Police has said that the Met is well resourced, and they are, and that they have very powerful counter-terrorism capabilities and they do.
"We have protected counter terrorism policing budgets, we have also provided funding for an increase in the number of armed police officers and since 2015 we have protected overall police budgets - and that's despite the fact that Jeremy Corbyn's Labour Party in the House of Commons suggested that police budgets could be cut.
"But it's also about the powers that we give to the police. We have given increased powers to the police to be able to deal with terrorists - powers which Jeremy Corbyn has boasted he has always opposed."
