Surgeons work by flashlight as Ukraine power grid battered

Dr. Oleh Duda, a cancer surgeon at a hospital in Lviv, Ukraine, was in the middle of a complicated, dangerous surgery when he heard explosions nearby. Moments later, the lights went out.

Duda had no choice but to keep working with only a headlamp for light. The lights came back when a generator kicked in three minutes later, but it felt like an eternity.

“These fateful minutes could have cost the patient his life,” Duda told The Associated Press.

The operation on a major artery took place Nov. 15, when the city in western Ukraine suffered blackouts as Russia unleashed yet another missile barrage on Ukraine’s power grid, damaging nearly 50% of the country’s energy facilities.
