It is two months since three members of a British family were killed while on a camping holiday in Annecy, southern France.

Saad Al-Hilli, his wife Iqbal and his mother-in-law Suhaila were shot dead in their car in a forest lay-by, along with a passing French cyclist, Sylvain Mollier.

Mr al-Hilli's daughters, Zainab and Zeena, survived.

French prosecutor Eric Maillaud has given an exclusive interview to the BBC in which he revealed new lines of inquiry.

The motive for the murders however, remains unclear. Christian Fraser reports.
