According to the Slovenian press, fire swept across a WWI-era bomb on July 22 and detonated it while firefighters worked nearby. Shrapnel buzzed the firefighters but no one was hurt. It’s just one of many such bombs that have exploded due to the fire; officials have stopped counting detonations due to their sheer number, local news reported, only marking ones that explode near roads.  > As first spotted by Task & Purpose, unexploded ordnance from World War I and II are a major problem in Europe. More than 1,000 firefighters and portions of the Slovenian military are working to contain the blaze, which has spread to almost 5,000 acres of land. “The problem is that because of the unexploded ordnance firefighting units cannot penetrate into the fire but can only act on its edges. This is why the fire is being intensively fought from the air as well,” Slovenian defense minister Marjan Šarec told the press.
