Fresh fog warning sparks misery with flights and trains axed

Thick fog has triggered disruption across Britain, with a yellow warning for fog in place until 11am. The Met Office warning covers areas from York to Bath and much of the South East and eastern England, with visibility dropping to 50m or less in places. Monday morning travel delays affected bus and train services and led to cancellations risk for flights. By 6.30am, seven flights from Heathrow and three from London City were cancelled. Drivers were urged to use fog lights when visibility falls below 100m. Separate crashes in fog caused injuries, including a multi-vehicle incident on the M20 in Kent.
