Norway’s Protector Forsikring is an insurer in a catastrophic blaze that roared through a 24-storey block of London flats, according to a Reuters report.

“As the insurance provider for Royal Borough of Kensington and Chelsea, Protector Forsikring ASA is involved in the tragic fire in Grenfell Tower,” Protector said in a statement. “Our thoughts go to the people who lived in the building and their families. Protector will work closely with the local authorities and rescue teams.”

At least 12 people were killed in the blaze, which engulfed the block after midnight Wednesday – although the death toll is expected to rise, according to a BBC report. At least 68 people were transported to hospitals, and at least 18 of them were in critical care. Another 10 transported themselves to the hospital, according to the BBC.

The cost of the fire will be covered mainly by Protector’s reinsurance program, according to Reuters.
