Rescuers raced against time Saturday in Kyushu to find those who disappeared in the aftermath of days of torrential rain that triggered deadly floods and mudslides across the island.

Rescuers are reporting severe difficulty navigating the massive amount of debris. They are trying to find as many people as possible in the crucial 72-hour period for surviving the deluge, which began on Wednesday.

On Saturday, the death toll rose to 18, with about 30 people missing.
