For more than 15 months the Ukrainian armed forces have held out against the superior numbers of the Russian invasion force. But not every Ukrainian man subject to the draft is willing to fight. More than 6,000 Ukrainian men of military age have been granted protection in Romania since the beginning of the war, according to figures supplied by the Romanian immigration authority. Some left Ukraine in order to avoid the draft. Others served on the front before throwing down their weapons. Romania has a 600-kilometre border with Ukraine, which is difficult to cross. The choice is either a short swim across a fast-moving river or a long trek over snow-covered mountains. A number of those who’ve tried have died in the attempt. Nick Thorpe has been to the border region to meet Ukrainian men who do not want to fight in the war.

Jean Vanier changed Richard and Hazel’s lives. He founded the L’Arche movement – a global network inspired by Christian teaching – where people with and without learning disabilities live together in community. During his life, Vanier was hailed as “a living saint” and “a prophet”. But shortly after his death, a deep and disturbing secret emerged – that Vanier founded L’Arche to hide a mystical sex sect, coercing and abusing at least 25 women, all without disabilities. Richard and Hazel were stunned when they discovered the truth. Now they and 150 L’Arche communities are coming to terms with what has happened.
