Investigators have identified the type of gun used in the killing of three members of a British family in the French Alps.
Iraqi-born Saad al-Hilli, 50, his wife and her mother and a cyclist were shot dead on Wednesday while on holiday.
Investigators say only one gun was used. Ballistics tests show 25 spent cartridges at the scene came from a 7.65mm calibre semi-automatic pistol.
The BBC reports that police have not formally revealed how many assailants they believe could have been involved at the scene.
