While some of the victims begged for help, others simply accepted their fate and said their goodbyes.
Khadija Saye, 24, who was in a flat on the 20th floor with her 54-year-old mother Mary Mendy, sent out a Facebook message reading “please pray for me” as smoke filled her flat.
Both mother and daughter are yet to be accounted for.
Saye, whose artwork has been featured at the prestigious Venice Biennale exhibition, was reportedly on Facebook Messenger until 3am, roughly three hours after the blaze started.
Her friend Nicola Green said: “She was on Facebook saying she was unable to get out of the flat, that the smoke was so thick.
“She was saying, ‘Please pray for me. There’s a fire. I can’t leave the flat. Please pray for me and my mum,’” Green said, according to the Daily Mail.
“At one point she’d tried to leave again and it was impossible. She said she felt like she was going to faint.”
Nura Jemal and her husband Hashim Kedir were among the families stuck in the 24-story tower and who were told to wait in their flats for emergency services to rescue them.
Her friend Asyia Assani said: “The lifts were not in use and the stairwell was filled with thick smoke so they were told it was not safe to leave.
“The emergency services said to stay inside and put a blanket at the bottom of the front door to block smoke getting in, and we’ll come and get you out.”
Assani said Jemal then got in contact with her again at 2am, this time to say farewell.
“Goodbye, I’m not going to make it. Please forgive me.”
A 12-year-old is still reportedly missing. Her last known whereabouts was a flat on the 20th floor.
Jessica Urbano sounded panicked as she called her mother in the early hours of Wednesday morning.
Her mother, an office cleaner, was returning from work when she tried to enter the building but was forced back by the flames.
She told the MailOnline: “Jessica called me. She was panicking. She said there was a fire.”
Witnesses said they saw the teenage schoolgirl being put in an ambulance, but the mother says she has not heard from her daughter since her call at 1:40am.

Although many residents are yet to be accounted for, police do not expect “to find anyone else alive.”
