Four children who are believed to be two sets of twins have died in a tragic London house blaze.

Eight fire engines and around 60 firefighters were called to an “intense blaze” at just before 7pm on Thursday night.

The first fire crews on scene were faced with a blaze throughout the whole of the ground floor.

The emergency services later confirmed that four children – all said to be under the age of five – had died in the tragedy.

Neighbours said they were two sets of twins, aged two and four, who were ‘sweet-natured and happy’, MyLondon reports.

Horrifying footage filmed on Thursday night shows an ‘intense fire’ raging inside the property, with flames coming out of a window.

Firefighters in breathing apparatus entered the mid-terrace house and brought four young children out of the property.

They were given immediate CPR by firefighters at the scene, who continued to administer treatment to assist London Ambulance Service crews on arrival.

All four children, believed to be related, were taken to hospital where, tragically and despite the efforts of all involved, were pronounced dead.
