Kings of Leon were forced to postpone a concert which was scheduled for London's O2 Arena last night after two of their tour buses went on fire.

According to The Telegraph, a spokesperson for the group said: ''Unfortunately, due to this morning's fire on board one of the tour buses at The O2, tonight's Kings of Leon concert will now be postponed."

"Whilst there is no damage to The O2, there is now insufficient time to rig the arena for tonight's performance."

"We are sorry for the inconvenience and we will announce a new date shortly."

The report also said that six people were treated for smoke inhalation after the fires.
