Donald Trump's suggestion that London police could have done more to prevent Friday's homemade bomb explosion drew a quick rejoinder from British Prime Minister Theresa May, who said it's never helpful "to speculate on what is an ongoing investigation."

Trump turned the London subway bomb explosion into an opportunity to highlight his tough talk on terror and promote his travel ban.

On Twitter, Trump called the explosion another attack "by a loser terrorist." He also offered implied criticism of law enforcement, saying "these are sick and demented people who were in the sights of Scotland Yard. Must be proactive!"

The London bomb exploded on a packed train during morning rush hour Friday, leaving at least 29 people injured. Police said the explosion was a terrorist attack.
