Firefighters in Brazil are calling for tens of thousands of people to be evacuated after a town was hit by a deadly mudslide that was triggered by a mining dam that ruptured. <br />Heavy rain has added to concerns a second dam in the area could also fail.<br />Lee Seung-jae reports. <br />Sirens began blaring before sunrise,... triggered by dangerously high water levels at a tailings dam near an iron ore mine in the southeastern town of Brumadinho. <br />Friday's burst dam unleashed a huge mudslide,... burying mining facilities and nearby homes. <br />Firefighters called on Sunday for the evacuation of some 24-thousand people,... as they fear a second dam nearby could collapse.<br />Over 300 people have been reported missing so far,... with the confirmed death toll surpassing 40. <br />Families and friends mourning their lost loved ones are being forced to up sticks and leave their homes.<br /><br />"I lost many friends, many colleagues. I am very sad, devastated. There are no words to speak because the pain is so great, I lost so many friends, my colleagues from haciendas lost cattle, they lost everything, everything, everything, everything." <br /><br />The disaster is deadlier than the 2015 tailings dam collapse at an iron ore mine less than 100 kilometers away,... when mining waste spilled into a remote region, killing 19 people, and burying a small village.<br />The spill contaminated a major river in what is still Brazil's worst environmental disaster on record.<br />The Brazilian government has ordered Vale, the company that owns the mining complex at the site of Friday's dam burst, to halt operations and it has frozen 1-point-6 billion dollars of the company's assets to pay for the damages caused so far.<br />What exactly caused the dam to burst remains unclear,... as officials say a recent inspection did not indicate any issues with the structure.<br />Lee Seung-jae, Arirang News. <br />
