In Bakhmut, Donetsk region, where heavy fighting is going on, famous American volunteer Pete Reed died. The Russians killed him on Thursday while assisting the civilian population.

Global Response Medicine said the volunteer was listed as "killed while rendering aid" while on a mission with another organization.

"GRM founder Pete Reed was killed in Bakhmut, Ukraine. Pete was the bedrock of GRM, serving as Board President for 4 years. In January, Pete stepped away from GRM to work with Global Outreach Doctors on their Ukraine mission and was killed while rendering aid," the statement said.

“This is a stark reminder of the perils rescue and aid workers face in conflict zones as they serve citizens caught in the crossfire. Pete was just 33 years old, but lived a life in service of others, first as a decorated US Marine and then in humanitarian aid. GRM will strive to honor his legacy and the selfless service he practiced," the statement said.

On the Global Outreach Doctors website, Pete Reed is listed as the director of the organization in Ukraine.

According to CNN, a spokesman for the US State Department confirmed in a comment "the recent death of a US citizen in Ukraine."

Reed's wife, Alex Kay Potter, revealed on Instagram that her husband not only lived for his duty, but apparently died saving the life of another team member.

“He was evacuating civilians and helping the wounded when his ambulance was fired upon. He died doing what gave him life and what he loved, and apparently saving a member of his team with his own body,” the wife noted.

Volunteer Pete Reed led medical teams during the Battle of Mosul in Iraq, treating more than 10,000 injured people.
