The cause of Wednesday's blaze in London is still under investigation, but anger has mounted in the community amid reports that exterior panelling used in an extensive renovation completed previous year may have helped the flames to spread.
Sharing the footage, Commander Stuart Cundy, said: "It is really important that we are clear about the scale of the challenge facing us as our teams search Grenfell Tower to recover those people still inside and return them to their loved ones".
Of the total 58 people missing, presumed dead by police, there are at least 30 confirmed deaths. Metropolitan Police Stuard Cundy said: "Sadly, our work will be ongoing for many, many weeks".
"In the wake of (the) Grenfell fire we have to recognise that something has gone badly, badly wrong in this country, that predominantly poor people die in a towering inferno because possibly in the long term (there had been a) lack of public investment", Mr Corbyn told ITV's Peston on Sunday programme.
