A nine-year-old girl who died following an asthma attack has become the first person in the UK to have air pollution listed as a cause of death.
Ella Kissi-Debrah, who lived near the South Circular Road in Lewisham, south-east London, died in 2013.
In the three years before her death, she had multiple seizures and was admitted to hospital 27 times.
Southwark Coroner's Court found that air pollution "made a material contribution" to Ella's death.
