Also in Europe, Serbian doctors observed a minute of silence on April 15 to mourn Miodrag Lazic, a famous surgeon who had died from an infection related to the coronavirus.

Lazic, 65, director of the Emergency Center in the City of Nis, had been on a ventilator because his condition was serious.

The Municipality of East Sarajevo fulfilled his last wish by playing the Serbian military song "March on the Drina" to honor their beloved doctor.

Lazic was "on the front line, until the very end ... until the moment when he found out that he himself had contracted the virus that, for months, had been relentlessly taking people's lives," said a statement issued by the Clinical Center of Nis.

"A man who was honorable, courageous and proud, side by side, on the front lines, stood by the Serbian army, in all the wars that struck our country and our people. A man, a doctor, a soldier who saved more than 1,000 lives on the battlefield," the statement added.

The specialist in surgery was a volunteer during the wars in former Yugoslavia in the early 1990s, and had written a book entitled The Diary of a War Surgeon.

So far, Serbia has reported 6,630 cases with 125 deaths, with the country being in a state of emergency since March 16.
