The shooting of a British family in France "was like something out of a Hollywood movie," a British man who was first on the scene has said.
Brett Martin helped seven-year-old Zainab al-Hilli after the attack which claimed the lives of her parents, grandmother and a local man.
He told the BBC he made the difficult decision to leave her bleeding on the ground while he went to seek help.
Meanwhile, a French prosecutor said the motives "have their origins" in the UK.
