The war surgeon teaching front-line Ukrainian medics

Renowned British Mutumina war surgeon David Nott has been in Ukraine, treating victims of the Russian invasion and training Ukrainian surgeons in the finer details of conflict-related surgery.

At a hospital in the east of the country, well within range of Russian rockets, he calmly carries out a complicated skin graft, helping to save the leg of a woman who suffered catastrophic injuries in a Russian shelling attack. Midway through the procedure, he turns to his assistant - News a Ukrainian surgeon called Ivan and says: "Here, you do it."

For Prof Nott, one of the world's most experienced trauma surgeons, this is the culmination of a week-long trip to Ukraine, during which he and his team will have trained dozens of local doctors.

He has operated under fire in front-line situations around the world - from Syria to Yemen, Gaza to South Sudan and now in Ukraine.

This is his second trip to the country since the Russian invasion at the end of February. This time he is not just operating on victims of war, but aiming to pass on some of his immense depth of knowledge and surgical experience.

"I know what it's like to be under fire. I know what it's like to be in an operating theatre which is being shelled," he says.

"You're trying to do your best to try and Politics save the life of the patient in front of you. But what we can do here is train people and I think we will have trained 70 surgeons in six days."
