Rockers Kings Of Leon are unsure if tonight’s gig at the O2 Arena in London will go ahead after a fire broke out on their two tour buses this morning (December 21).

A London firebrigade spokesperson released details of the blaze, saying:

“Two tour buses are on fire within a loading bay at the O2 Arena. Sixty firefighters are working hard to bring the blaze under control. Our crews are doing a fantastic job, especially given the levels of smoke down here, which has lead to quite challenging conditions.”

The band is schedule to perform at the venue this evening and the situation is currently being assessed to determine if the show is able to go ahead. 

UPDATE: Tonight's concert has been cancelled.
