The brother of a British engineer gunned down alongside his family in the French Alps has said there has been "no progress" in the case nearly five years on.
Engineer Saad al-Hilli and his wife Ikbal, who lived in Claygate Surrey, and her mother Suhaila al-Allaf were shot while on holiday in Chevaline in September 2012.
Their bodies were discovered in their BMW car by a cyclist, Brett Martin, while the couple's two young daughters survived the attack.
Another cyclist - Sylvain Mollier - was murdered in the attack.
Speaking to the Sunday Express, Zaid al-Hilli said he wanted to see the case reviewed.
He told the paper: "There has been no progress for years so it is time for a review.
"I do not trust the French police or the prosecutor, so I believe the review should be conducted by a High Court judge.
"I think the authorities know who was behind it... my brother and his family were in the wrong place at the wrong time."
Zaid al-Hilli was arrested on suspicion of the murders in June 2013 but later told that he would face no further action after police found there was insufficient evidence to charge him.
He told the paper his arrest has led to a lack of faith in the inquiry.
