Lithuania’s minister of defense, Dovile Sakaliene said the search for four US Army soldiers who went missing during a scheduled training exercise near Pabradė, Lithuania, has shifted from rescue to recovery mission.

The search for four U.S. Army soldiers who went missing Tuesday during a training session in Lithuania continued this weekend, officials said. The soldiers went missing after their M88 Hercules armored vehicle became submerged in a peat bog during the training exercise with Lithuanian armed forces and law enforcement.
