A U.S. armored vehicle that went missing in Lithuania has been retrieved from a swamp after a six-day search but there is still no information about the fate of the four American soldiers who were on board, Lithuanian officials said Monday.

This comes as US and Lithuanian forces continued to drain a swampy area in Lithuania to recover four American Army soldiers who went missing on 26 March. The soldiers' armored vehicle was discovered submerged in 15 feet of water. The soldiers were on a mission to recover another Army vehicle during unit training.
