Two children killed by falling tree in Yosemite National Park

YOSEMITE NATIONAL PARK, Calif.  (KTVU) -- Two children were killed early Friday as they slept inside their tent by a falling tree at Yosemite National Park, officials said.

Park officials said that at approximately 5:00 a.m. a limb from an oak tree fell in Upper Pines Campground in Yosemite Valley, striking a tent in which two minors were sleeping.

Park Rangers responded to the campground to provide medical assistance, but the minors were declared dead at the scene.

The names, ages, and places of residence of the victims are not being released. The incident remains under investigation.

"Our thoughts are with the families as they grieve this tragedy," stated park Superintendent Don Neubacher.  

In 2013, a Camp Tawonga counselor Annais Rittenberg from Santa Cruz was killed when a large tree fell onto the campfire circle outside of the dining hall just before 8:30 a.m.
