A bomb disposal unit has been called to the house of a British couple killed in the French Alps last Wednesday.

Police have evacuated homes near the al-Hillis' family home in Surrey, saying they are concerned about items found at the property.

Saad al-Hilli, his wife Iqbal, her mother and a French cyclist were shot near Lake Annecy.

The BBC's Keith Doyle reports.
