Police in London confirm that two British-Bangladeshi women were killed in the deadly Grenfell Tower inferno.

Residents of 800 London flats were hurriedly evacuated Saturday due to fire safety fears over their tower blocks' external cladding, after urgent testing prompted by the deadly Grenfell Tower inferno.

A fire that killed at least 79 people at a London apartment block started in a freezer, and the outside cladding engulfed by the blaze has since been shown to fail all safety tests, London police say.

Architect Gloria Trevisan talked on the phone with her family in Italy when she died-- another victim of the inferno at London's Grenfell Tower, says CNN quoting victim's family attorney.

Prime Minister Sheikh Hasina expresses her deep condolences over the deaths caused by the fire in London tower block which killed at least 30 people.

The death toll from the London tower block fire has risen to at least 30 and police are considering whether criminal offences had been committed, a senior police officer says.
