About 30 Ukrainian men have died trying to illegally cross Ukraine's borders and avoid fighting in the war against Russia which started in 2022, the spokesman for Ukraine's border service told Ukrinform news agency. "Some lost their lives while attempting to cross a mountain river or traverse mountains," said Andriy Demchenko, according to a Ukrinform report late on Monday. With some exceptions, Ukrainian men between the ages of 18 and 60 are not allowed to leave the country as they may be mobilised to fight, according to Ukraine's martial law.
