Rescue teams are attempting to free 12 workers trapped in a copper mine in southeast Turkey.<br /><br /> At least four people were killed when a landslide hit the mine near the town of Sirvan in Siirt province.<br /><br /> The local governor has launched an investigation, but the private owner of the mine believes heavy rains triggered the landslide which caused the collapse.<br /><br /> Families of the miners watched as more than 90 rescuers worked to free their loved ones.<br /><br /> The country’s recent construction boom has seen workplace accidents rise, as safety standards fail to keep pace. The worst mining accident occurred in May 2014, when an explosion at a mine in Soma left 301 people dead.<br />
