Authorities say a landslide has wiped out a group of poor homes in central Bosnia, killing one woman and injuring three other people.

Rescuers searched for hours before they pulled out two children and a woman alive early Monday morning from the rubble.

Seven homes were destroyed when the slope they stood on slid down 500 meters (550 yards) in the town of Kakanj.

The houses were built on top of a coal mine that was closed 50 years ago. None of the homes had a building permit as the area was considered risky. But illegal building is widespread as Bosnia has struggled with poverty since the end of the Balkans war in the 1990s.
