A man has been arrested on suspicion of murder after a woman died in a fire at a block of flats in east London, police have said.
At least five other people were taken to hospital with injuries after the incident on Thursday in Beckton in Newham.

The LFB said the first and second floors of the residential block were alight, along with the staircase from the first to the second floor.
The Met said: “Police were called at approximately 17:28hrs on Thursday 6 April to reports of a fire at a block of flats in Tollgate Road, E6.

An LFB spokesperson said: “The cause of the fire is not known at this time.”
An LAS spokesperson said one person died at the scene and paramedics treated five others who were then taken to hospital.
