Two campers died when a tree limb fell on their tent in California's Yosemite National Park. The large tree branch fell on the young campers when they were sleeping in their tent in the park.

Providing more information on the accident that took place on Friday, Yosemite spokesperson Scott Gediman said it was a black oak limb fell that fell on the tent of the two campers. They were sleeping at the heart of the park when the accident happened, Gediman added.

According to Gediman, the young campers were under 18. Rangers received 911 calls reporting about the accident. When the rangers reached the location, both the campers had died, he said. Gediman did not provide information on what caused the oak tree limb to fall on camper, or what was the size of the limb.

It was not the first accident of its kind at Yosemite; such limb fall incidents are common there, and some of them occasionally led to deaths. In 2012, a park employee died when a limb fell on his tent cabin. About 30 years ago, two individuals were killed when a huge limb fell onto a tram.

After Friday’s incident, park officials announced to temporarily close a nearby popular campsite. The California Department of Health said, “Tuolumne Meadows Campground will close from noon Monday through noon Friday so authorities can treat the area with a flea-killing insecticide. Campers had their reservations canceled at the 304-site campground so the insecticide can be sprayed into rodent burrow holes”.
