1108 GMT - United Airlines says it is cancelling flights to London Heathrow that were planned for Friday following the closure of the airport. The U.S. airline says seven of its flights had to return to their origin or to other airports following the incident and that it is working to offer customers affected by the disruption alternative travel options. London Heathrow, one of the busiest international airports in the world, had to close due to a sudden fire at a nearby electrical substation that supplies it with power and has warned of significant disruptions over the coming days.
