A man whose mother and sister died in the Grenfell Tower fire was given a standing ovation as he described helplessly waiting on the phone as they succumbed to the flames.

Ahmed Elgwahry, said he was on the phone to his younger sister, Mariem Elgwahry, 27, and she and Eslah Elgwahry, 64, took refuge on the top floor of the high-rise block.

Speaking slowly and calmly, Mr Elgwahry described how he stood at the bottom of the tower and realised that running in to try to save them would have been an act of suicide.

He told the inquiry on its sixth day of commemorative hearings: "On my final call with Mariem, despite her suffering, despite her gradual deterioration, despite her gradual loss of consciousness, she persisted in letting me know that she was still there.

"She started fading away from me rather rapidly, but she kept going all the way until she was no longer audible. She started to mumble, started banging the floor, and then finally no longer responsive.

"It was at this point I presumed I lost my mum at the same time. But then about 20 seconds later, for the first time that early morning, I heard my mum's voice.

"She was struggling for breath, and said her last words: 'I can't breathe, I can't breathe'. That was the last time I heard her voice. She was so frightened that she had not spoken prior to this."

He disconnected the call more than an hour after their final moments, he said.

All he could hear was the crackle of fire.

Months later, only fragments of their bodies were recovered by the coroner and her team, who attempted to piece them back together "bone for bone, as if they were dinosaurs".

Two weeks of poignant tributes from family and friends remembering Grenfell Tower fire victims will be heard by the public inquiry

Mr Elgwahry's father died years ago from an aggressive form of cancer, he said.

But on the night of the fire, he said he "felt like my father died again and a large part of our life, important memories were wiped out, erased in a matter of minutes".

The commemorations are being heard at the Millennium Gloucester Hotel in South Kensington .

Eleven other victims will also be remembered on Tuesday (May 29), including five-year-old Isaac Paulos.
