At least 30 people have died and 12 people are in critical care after a huge fire engulfed a west London tower block on Tuesday night.
Many people are unaccounted for, and 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.
Brkite and Biruk Haftom
Mother and son Brkite and Biruk Hafton live in Flat 155 of Grenfell Tower.
Family friend Dejan Araya says Brkite's sister and friend have been searching hospitals for news of their whereabouts and are inconsolable.
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
Deborah Lamprell, 45, lives on the 16th floor. A family friend said she would always text her mother when she returned home from work.
The last text message Ms Lamprell sent her mother was at about 23:30 BST on the evening of the fire. She has not been heard from since.
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.
"We haven't had any news and don't know if she's been rescued and in hospital."
Gloria Trevisan and Marco Gottardi
It is believed Mr Gottardi, and his girlfriend Ms Trevisan were staying with friends at Grenfell Tower.
Mr Gottardi's father Giannino told Italy's ANSA news agency that he had been on the phone to his son and his girlfriend up until the last minute.
He told him that the flat was full of smoke and then communications were interrupted.
"We're just hoping for a miracle," he said.
Mr Gottardi, an architect, is from a town near Venice and Ms Trevisan is from the city of Padua.
El-Wahabi family
Five members of the El-Wahabi family are missing. Sanaa Jones says they are her uncle Abdul Aziz, 52, his wife Fouzia, 42, son Yasin, 21, daughter Nur Huda, 15, and youngest son Medhi, 8.
Sanaa's other aunt, her husband, and two children - who also live in the same block - were able to escape from the sixth floor, but the El-Wahabis were on the 21st floor.
My aunty told my uncle to get out but there was a lot of smoke," she said
"My uncle got on the phone to the fire brigade, who advised him to stay inside and to shut the door, and put blankets down around 02.30.
"That's the last time we heard from them.
"I went to one hospital, my cousins went to other hospitals. There is nothing and they are not there.
"It's very distressing time at the moment. We have to try to keep strong."
Hamid Kani
Iranian born Hamid Kani, 61, lived alone in flat 154 of Grenfell Tower. A London-based family friend says his relatives in Iran are devastated as they cannot reach him.
