Twenty-two people were injured in a bomb blast on a packed London Underground train on Friday, the National Health Service said in a statement.
"Yesterday we saw a cowardly and indiscriminate attack which could have resulted in many lives being lost", she said.
Scotland Yard also reportedly commented on Trump's tweet saying that it was "unhelpful and pure speculation". He also attacked London Mayor Sadiq Khan's response to the attack, prompting Khan to call on United Kingdom officials to cancel the president's upcoming visit. His hasty tweets about London stand in stark contrast to the notable crickets surrounding Charlottesville, proof that timing really does say it all.
Trump, who spoke briefly with reporters before going into the Oval Office, said he had been briefed on the attack, which police called a terror incident, calling it a "terrible thing". "It keeps going and going, and we have to be very smart and we have to be very, very tough perhaps we're not almost tough enough", Trump told reporters in the Rose Garden of the White House.
Bank of Canada Surprises With Another Rate Rise
Interestingly, the BoC did also reference elevated household indebtedness and the impact that these rate rises could have on it. The Canadian dollar initially surged on the news to a fresh two-year high, although it pared back some of the early gains.
Trump had referred to his travel ban back in June immediately after the London Bridge terror attacks.
The official said that at this point, US agencies had no information to back up any suggestion by Trump that Britain had advance warning or specific intelligence on the attack.
"It's a bad thing", he said of the London attack. He and his son Donald Trump Jr both mocked Sadiq Khan after taking the mayor's words of reassurance to Londoners out of context.
Trump has repeatedly pointed to his travel ban as a cornerstone of his counterterrorism platform. "Must be proactive!" Trump said in one tweet. "We need the Travel Ban as an extra level of safety!"
The version of the ban permitted by the Supreme Court is Trump's second pass at the policy, which originally banned residents of seven Muslim-majority countries. Trump's executive order also requires reports on its effectiveness.
