PANAMA CITY, Panama – Two U.S. soldiers died and two others were injured in a traffic accident in northwestern Panama, emergency personnel reported Friday.

The U.S. Embassy identified the dead as Brad A. Svoboda of Maine and Christopher Conn of California. Details on their hometowns or units were not immediately released.

The Army reservists were traveling in a Humvee on Thursday when it was struck by a truck near the town of Miramar, about 300 miles west of the capital.

One of the reservists was declared dead at the scene and another died hours later, said Roberto Velasquez, director of the National Civil Protection System.

Two other reservists suffered less severe injuries in the crash, the embassy said. A Panamanian traveling in the Humvee also was injured, as well as the driver of the truck.

In the western province of Bocas del Toro, reserve units are building schools and health clinics, and providing medical assistance for local residents.
