Rescue workers from the European Union, Russia and Turkey have been helping stranded people and delivering food, blankets, generators and clean water to those in shelters. There have also been reports of thousands of dead animals — cows, sheep, pigs and dogs — washing up as floodwaters have receded.
About 2 million land mines were planted during Bosnia's civil war. The mine action center helped remove most of them. Only 120,000 remained in a 460-square-mile area, marked by some 25,000 signs.
"We spent 10 years marking this area with warning signs," Ahdin Orahovac, the center's deputy director, tells NPR. "In these few days, everything is gone."
Land mines have killed about 1,800 Bosnians since the end of the war, so people are aware of the danger, Orahovac says. Several people in flood-affected areas have already called to report discovering several bombs, grenades and other unexploded ordnance, he says.
"Our message to everyone that calls is: Don't touch these things. Wait for us or rescue workers to come," he says. "So I hope this works, and there will not be accidents."
His team is also mapping each report of a found land mine.
"This is a slow and expensive process, but we don't have time," he says. "It's complicated. We are going to need special teams and money. We are going to need help from outside."
There are also fears that waters and mudslides have pushed some land mines into neighboring countries. The mine action center is working with Republika Srpska (the Bosnian Serb republic) as well as Serbia and Croatia to deal with land mines that rivers have likely swept past borders.
