The military and firefighters are continuing the search for 4 U.S. soldiers who went missing at a training ground in Podbrudzie, Lithuania. So far, rescuers have failed to extract the armored vehicle from the body of water, and as a result, it is unclear whether the soldiers were inside, said Lithuanian defence Ministry chief Dovile Szakaliene, who arrived at the training ground with the country's Prime Minister Gintautas Paluckas on Thursday.
