Several people are feared dead after a fire tore through the Grenfell tower block in West London in the early hours of Wednesday morning. At least 60 people are being treated in hospital.
Videos posted to social media have shown the horror in North Kensington as a blaze rips through a 24-storey block of flats.
One shows the moment a brave firefighter continues to tackle a ferocious blaze despite being showered with flaming debris.
Other videos show children screaming for help as families try to escape the blaze. In another, a witness describes the moment he saw a child on fire fall from the 22nd floor.
The fire broke out at around 1am on Wednesday morning and quickly took hold of the Grenfell tower in north Kensington.
In one video, filmed on Periscope by a resident of a neighbouring tower, one of the firefighters attempts to calm the flames while standing in a cherry picker.
Although he is showered with debris, he carries on.
Dramatic videos show flames licking the side of the 24-storey building as residents desperately screamed for help.
One harrowing video shows people attempting to make ropes from blankets to climb down to safety.
London Fire Commissioner Dany Cotton and the Mayor of London Sadiq Khan have declared the fire a major incident.
The brigade arrived at the scene within six minutes of the first call, sending 200 firefighters from 40 stations. Many of the residents made it out, but some have claimed the fire alarms did not sound.
Fatalities have been confirmed, but the number is not yet known. Five hospitals are treating more than 50 people.
Eyewitness accounts tell of the speed at which the flames took hold after starting on the fourth floor.
