Fears are growing for people who are unaccounted for after a huge fire raced through an apartment block in West London and left at least six dead.
Between 400 and 600 people are said to live in the building, which houses 120 apartments and was still burning some 14 hours after the blaze broke out in the early hours of Wednesday. It is unclear how many people were inside the building at the time and how many were able to escape. Authorities asked residents who had escaped to contact a help line so that they could be accounted for.
Metropolitan Police Commander Stuart Cundy says he anticipated "that there may be people within that building that are as yet unaccounted for."

The former deputy chief fire officer for U.S. Air Force bases in Britain says he has never seen a fire in an apartment block spread at such speed.
