The soldiers' conditions have been described as stable, according to doctors.

"Yesterday three soldiers with severe injuries were brought, one of them in a state of clinical death. Fortunately, the patient was returned to consciousness – special thanks to our emergency physicians – and the operation was carried out. We could save only one leg, with 3.5 liters of blood being transfused. The patient's condition has stabilized," said Vladyslav Yatsun, the coordinator of the medical reinforcement group.
