The mother who died alongside her three children in a horror house fire was pregnant, her heartbroken neighbours have revealed.

The 43-year-old, a 15-year-old girl, and two boys - aged eight and four - were found dead at the family home in Tillett Close in Stonebridge, north west London in the early hours of Saturday morning.

Two other members from the same family, a 70-year-old woman and a teenage girl, were rushed to hospital for treatment.

Devastated neighbours raised the alarm at 1am when they saw flames coming from the building and later heard 'small explosions'.

They described them as a 'nice family' with one saying the woman was expecting another child.
