Teams have begun searching a landfill site as part of an investigation into the disappearance of RAF airman Corrie Mckeague.

The 23-year-old vanished while on a night out with friends in Bury St Edmunds, Suffolk, in September.

A bin lorry collected refuse a short time later from the area the RAF Honington gunner was last seen.

The search of the site, in Milton, near Cambridge, could take up to 10 weeks, police said.
