At least 30 people have died and the BBC understands that about 70 are missing after a huge fire engulfed a west London tower block on Tuesday night.
It is likely that the 30 are among the 70 people missing but this is not known for certain.
There are 24 patients still in hospital, 12 of those in critical care after the blaze in Grenfall Tower.
Loved ones have appealed on social media for information. An emergency number – 0800 0961 233 – has been set up for anyone concerned about friends or family.
Omar Belkadi, Farah Hamdan and Leena Belkadi
Omar Belkadi and his wife Farah Hamdan are unaccounted for, as well as their six-month-old baby, Leena.
The couple lived on the 20th floor of the block. Two of their children, who are eight and 10, were found alive in hospital.
Farah’s cousin Adel Chaoui told the BBC that Farah called her sister while the fire was raging to ask for advice.
“When we told them to get out, Farah said she was told to stay put, not to go anywhere,” he said.
“That was the last we heard.
“We don’t know whether the authorities got up to the 20th floor to find the children. We’ve had no more information from them.”

Dejan Araya said the last time there was any contact with them was at around 22:00 BST on the night of the fire.
Deborah Lamprell, 45, lives on the 16th floor. A family friend said she would always text her mother when she returned home from work.

Ms Lamprell’s cousin made an appeal on Facebook for information. She posted: “Dear friends, I am desperate for your help. My cousin Deborah Lamprell lives in Grenfell Tower.

He rushed to the tower and spoke to them on the phone asking them to flee.

Another family member, Mr Nurul Islam, expressed his anger on Friday that he feels the council and government are providing insufficient help and resources on the ground at Grenfell Tower.
“Where are government officials? Where are council officials?” he said.
“There isn’t any leadership or co-ordination – the Red Cross and Muslim Aid are here, but they are charities, they are not people who’ve been elected to support us in times of need.”
The family of 66-year-old retired lorry driver Tony Disson told the BBC he lived on the 22nd floor of Grenfell Tower.
