All four U.S. soldiers who had been at the center of a recovery mission in Lithuania for a week after their armored vehicle sank in a peat bog near the border with Belarus have been found dead, the Army said.

The body of a fourth U.S. soldier missing in Lithuania was recovered Tuesday, U.S. Army Europe and Africa officials said, a day after rescuers recovered three other soldiers who died last week after their armored vehicle sunk into a bog.

The three soldiers were been found dead in their armored vehicle that was pulled from a swampy area early Monday, the Army said.
