Serbian rescue workers drive their way through the flooded town of Obrenovac, 40 kilometers west of Belgrade, on May 18, 2014. Thousands of people crammed into boats and army trucks fled their homes in Serbia and Bosnia today after record rainfall turned the Sava river into a deadly torrent and caused the worst floods in more than a century. According to officials in both countries, the disaster has killed at least 44 people. AFP PHOTO / ALEXA STANKOVIC        (Photo credit should read ALEXA STANKOVIC/AFP/Getty Images)
