KUALA LUMPUR, Malaysia — Rescuers recovered the bodies of 11 more climbers from Malaysia’s highest peak on Saturday, a day after it was struck by a strong earthquake, raising the total number of dead to 13.

Six people remained missing on 13,435-foot-high Mount Kinabalu, in eastern Sabah State on Borneo, where a magnitude 5.9 earthquake on Friday sent rocks and boulders raining down the trekking routes, trapping dozens of climbers.

“This is a very sad day for Kinabalu,” said Sabah’s tourism minister, Masidi Manjun.

Nine of the bodies found Saturday were flown out by helicopter, while the other two were moved down by foot, said a district police official, Farhan Lee Abdullah.

Most of the other climbers made it down the mountain in the darkness early Saturday, some with broken limbs. One was in a coma.
