British Prime Minister Theresa May said on Friday it was not helpful for anyone to speculate on investigations after U.S. President Donald Trump tweeted that the culprits behind a train bombing had been "in the sights" of the police.
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".
Scotland Yard said it was "too early" to confirm the cause of the blast during the Friday morning rush-hour, which saw 18 people taken to hospital.
Must be proactive! Loser terrorists must be dealt with in a much tougher manner. He added. "The internet is their main recruitment tool which we must cut off & use better!"
The bomb rocked a London Underground train, injuring 29 people.
Others chimed in, with May's former chief of staff, Nick Timothy, saying Trump's comment was "so unhelpful from leader of our ally and intelligence partner".
Among his first actions after taking office in January was to order a ban on all citizens from seven Muslim-majority nations - Iran, Iraq, Yemen, Syria, Sudan, Libya and Somalia from entering the United States for 90 days and all refugees for 180 days, later struck down by the courts. Neither the Metropolitan Police nor the British government have said anything publicly behind describing the detonation as a suspected terrorist attack.
Following the London Bridge terrorist attack, Trump criticized Khan for saying there was "no reason to be alarmed".
"I wanted to make sure, unlike most politicians, that what I said was correct, not make a quick statement", Trump said, adding, "Y$3 ou don't make statements that direct unless you know the facts".
May protested to Trump after US officials leaked information about a deadly bombing in Manchester in May.
Along with advocating for a "larger, tougher" travel ban, the President also suggested shutting down the internet.
"We need to be smart, vigilant and tough". The Supreme Court is scheduled to hear arguments on October 10 on the legality of the bans on travelers from six mostly Muslim countries and refugees anywhere in the world. Must be proactive & nasty!'
