The partially blind man was seen at the window of his flat during the blaze

Good Morning Britain viewers have voiced their shock and sadness after the programme aired upsetting footage of an elderly man trapped in the London tower block fire.

The man – thought to be partially blind and in his 70s – was seen at the window of his 11th floor flat during the blaze at Grenfell Tower which engulfed the building overnight.

He appeared to be praying and pleading for help as smoke billowed near the window.

During the morning GMB showed live footage of the resident, with Susanna Reid telling viewers: ‘He in his 70s, he’s partially blind. He has lived in the Grenfell Tower for 30 years.

‘Now we have seen him over the course of the last hour or so in contact with fire fighters.’

Piers Morgan also added: ‘You feel just helpless. We’ve been watching this guy for hours.

‘The fire fighters are doing all they can, it goes without saying they’re risking their lives, some of them may have lost their lives we don’t know.

‘We’ve been watching this guy for hours. Is there nothing else we can do to help him?’
