The attack on a Tube carriage in Parsons Green and the ongoing manhunt dominate several of the front pages.
Pictured on The Daily Mail, The Mirror and The Sun is the smouldering bucket bomb but The Sun says the device's timer malfunctioned, setting it off earlier than planned.
The Telegraph agrees the south-west London station was probably not the intended target adding that Westminster was more likely.
Internet companies are accused of having "blood on their hands" by The Daily Mail. It says reporters who logged on to Google took a matter of minutes to find the plans to build a bucket bomb.
The paper reports Prime Minister Theresa May will order the internet giants to clamp down on extremism. Google told the paper it removes links to illegal content as soon as it is notified.
Meanwhile The Express asks whether the police knew the tube bomber, referring to Donald Trump's remark that the perpetrator had been "in the sights" of Scotland Yard.
But The Times says it has been told by sources that the US President had not been briefed by British security services and no fact-sharing arrangement was in place when Mr Trump made his intervention.
Foreign Secretary Boris Johnson's "grand vision" for Britain after Brexit is revealed in The Telegraph.
In his 4,000 word article for the paper, Mr Johnson argues the UK is not about to despair of finding the way out of the EU and sit down and cry like a toddler lost in the maze at Hampton Court.
The foreign secretary also attacks the idea of remaining in the single market and the customs union. He warns this is an "invertebrate position" which "betrays a dismal lack of confidence".
In its editorial, The Telegraph says he has offered a bold, optimistic, unifying vision for a country where "regulation" and "taxation" are kept to a minimum. Its former editor, Charles Moore, thinks Mr Johnson is making a leadership bid by getting in first when everyone was planning to take the Conservative party conference next month quietly.
Meanwhile, the Financial Times puts a price tag on Jeremy Corbyn's suggestion that a Labour government would write off the debts of students who had been to university since 2012.
It quotes research by the Institute for Fiscal Studies showing this would add £60 billion to the national debt. This would be, the paper says, on top of the £11 billion a year cost of abolishing fees for future students.
The Sun points out that wiping out student debt would aid graduates with higher salaries, as they end up paying back the most.
Plumbers' rates not equal
The Times covers research showing plumbers are routinely overcharging women and old people.
The study deployed a middle aged woman, a middle aged man and an elderly gentleman to get quotes for the same job from ninety firms across England.
It found the male caller was quoted £74 on average; the female caller £86 and the older man, £90. The greatest differences between the sexes, according to the paper, was in north-east England.
