Four foreign hikers who had been missing for days in a mountainous area of the central Philippines were rescued Saturday, local authorities said, a day after their two companions were found safe.

The six-man group, which included German, British, Russian and Canadian nationals, had set out on Wednesday for what was to be a four-hour excursion in an area of Negros Oriental province officials said was hit by a downpour.

“The army rescuers found them in the vicinity of the Silab hydropower plant,” said Jose Lawrence Silorio, a rescue official in the municipality of Amlan, near the province’s Balinsasayao Twin Lakes Natural Park.

Police identified the four men as Germans Aldwin Fink, 60, and Wolfgang Schlenker, 67; Russian Anton Chernov, 38; and 50-year-old Canadian Terry de Gunten.

Philippine Army personnel found the hikers in a mountainous area thick with vegetation, said investigator Leo Gil Villafranca.
