The president weighed in as police in and around London carried out a manhunt for the person or persons who set off a crude incendiary bomb on a subway auto during Friday's morning rush hour.
Police say several people have been injured in the rush-hour incident on a Tube train at Parsons Green station in west London.

He also took the opportunity of Friday morning's incident to call for a stricter travel ban - one that has been staunchly opposed by the tech industry. According to the White House, Trump expressed sympathy for the people injured and promised to continue working with the British to fight terrorism. 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.
