Christopher is the son of one of the two French humanitarian workers killed in Ukraine. He wants to put an end to rumors that his father was a mercenary.

"I don't think he died unhappy. Because he did what he wanted in his life," he says. "He wanted to end his career doing noble causes, helping people in need," he adds. 'I was woken up by my grandmother who said to me, 'Dad is dead' 'I want to end rumors that my father was not a mercenary, but a man who wanted to help people,' he says, adding that he is proud of his father.
