New search for missing toddler Ben Needham begins on Kos island

Police teams searching for missing toddler Ben Needham on the Greek island of Kos say they are "optimistic" a new excavation will provide answers, a quarter of a century after the British boy was last seen alive.

Digging began after a fresh line of inquiry suggested 21-month-old Ben may have been crushed to death by a digger near a farmhouse his grandparents were renovating in July 1991.
