"The lost city" is the i newspaper's headline, as many papers carry pictures of the ruined port area of Beirut or the desperate efforts of rescue teams looking for survivors.
Much of the coverage focuses on how there had been repeated warnings about the dangers posed by storing the cargo of ammonium nitrate.
"Beirut explosion risks were ignored" is the claim of the Guardian as it details mounting anger in the Lebanese capital.
Concerns over the new assessment methods replacing exams for schoolchildren this year because of the Covid-19 crisis also receive prominent coverage. "Pupils face exam chaos 'life sentence" is the headline in the Daily Telegraph.
It reports the view of Dr Martin Stephen - the former head of St Paul's Boys school in London - who worries that the life chances of students could be permanently affected by restrictions on appeals. The only grounds for appeal will be technical ones, such as an irregularity in process, rather than because they feel they've been given an unfair mark.
A headline in the Huff Post declares that the government is under pressure to avoid "an exam results 'disaster' that hurts the poorest".
It details how, as education bosses grappled with the first school year without exams, Scottish politicians came under fire because moderated results appeared to favour those from affluent backgrounds.
Along with several papers, it reports that Labour has written to Education Secretary Gavin Williamson seeking "urgent reassurance" the same will not be repeated south of the border next week.
The Scottish regulator says the most disadvantaged young people achieved better results in 2020 than in 2019 or than the average results for the last four years.
Proposals for a shake-up of planning in England are the lead for the Times.
"Red tape to be slashed" is the headline as it reports that the government's white paper will allow for quicker approval for homes, schools, and hospitals, with councils losing the power to block developments.
It is the main story for the Guardian too, which carries a warning from charities and architects that the "rushed" shake-up will lead to "more slums".
The Sun takes a different view: its headline declares, "In hod we trust". It reports that the Housing Secretary Robert Jenrick will unveil reforms that will not only be a bonanza for brickies, but that will help kickstart the economy.
The paper says "Rob the Builder", as it christens Mr Jenrick, wants small and medium-sized firms to build a substantial chunk of the 300,000 new homes each year.
Its editorial backs the plan. "Bring on the revolution," it says, arguing the changes will be a godsend for a generation priced out of the housing market, while ensuring fairer competition in construction.
"Jail killers of 999 workers for life" is the main headline for the Daily Express. Its front page is given over to the launch of an appeal by Lissie Harper - the widow of PC Andrew Harper - calling for an "Andrew's Law" to ensure anyone who kills an emergency worker is locked up for life.
Metro and the Times also provide coverage of the campaign, quoting Mrs Harper saying she wants to ensure that anyone else who has to go through the loss she has experienced will "get the justice they rightly deserve".
The Guardian's front page carries a claim that attitudes to the menopause are "forcing NHS medics out".
It is based on research carried out by the British Medical Association which found that 90% of the 2,000 doctors who responded said menopause symptoms had affected their working lives.
Two-fifths said they were unable to make changes to working patterns to cope better. Almost half said they had not felt comfortable discussing the issue because of stigma and potential career blight - with many leaving GP partnerships and ending their positions as clinical leaders and directors as a result.
The doctors' union tells the paper that experienced staff should not be forced to make that choice because of inflexibility during a relatively short phase of life.
And the Times reports that the Cecil Rhodes Museum in Hertfordshire has decided to formally change its name later this month following the Black Lives Matters campaign.
The complex in Bishop's Stortford, where the colonialist was born, will be known as South Mill Arts from 24 August. The trust that runs it will no longer be known as the Rhodes Birthplace Trust.
Officials said the decision had been taken after the community's views had been expressed in emails and social media debate. They insisted that Cecil Rhodes would not be eradicated from the town's history.
