Former Marine killed in Ukraine while giving aid to wounded

• The U.S. government has discouraged Americans from fighting in Ukraine over concerns that they may be taken hostage by Russian forces.

Driving the news: Reed, 33, was evacuating civilians in Bakhmut and responding to the wounded when the shelling occurred, his wife, Alex Potter, said in a post.

• He'd stepped away from his charity last month to work with Global Outreach Doctors on their mission in Ukraine and was killed while rendering aid, according to Global Response Medicine.

What they're saying: "He died doing what he was great at, what gave him life, and what he loved, and apparently by saving a team member with his own body," his wife 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," the charity said.
