The second biggest city in Ukraine, Kharkiv, is just 30 kilometers from the Russian border. Under siege by Russian troops for more than six months, the city suffered major damage but never fell.

Everyone says they’re prepared for a new invasion, but the past haunts the future of its residents. Marcus Harton narrates this report from Yan Boechat in Kharkiv.
