Heathrow fire: Too early to speculate on cause, UK PM's spokesman says

'It's too early to say what has caused fire, and I would caution you against speculating, there'll be a time for a thorough investigation,' the spokesperson said.

London: A spokesman for British Prime Minister Keir Starmer said on Friday that it was too early to speculate on the cause of a fire that knocked out power at Heathrow Airport, stranding passengers around the world.

"It's too early to say what has caused fire, and I would caution you against speculating, there'll be a time for a thorough investigation," the spokesman told reporters.

"There are questions to answer, we expect those questions to be answered, but our priority right now is on this incident being appropriately dealt with. There is a fire still burning."
