HONG KONG — A weeklong, round-the-clock search for victims of a landslide that may have buried dozens of miners in Indonesia is still underway, a rescue official said Tuesday, as the confirmed death toll rose to 17.

The landslide, which struck on Feb. 26 on the island of Sulawesi, left an unknown number of miners trapped underground. As of Tuesday, rescue personnel combing the steep jungle terrain with earth movers had found 18 survivors, and the death toll had risen from nine a day earlier.

“We have no exact number of the people down there, or even how many small holes there are,” Yusuf Latif, a spokesman for Indonesia’s search and rescue agency, said by telephone.

He added that in addition to 17 dead, the authorities had found body parts that they were working to identify.
