About 3.500 acres have reportedly burned by a fast-moving grass fire on both sides of the Cajon Pass. The fire has shut down part of Interstate 15 Friday, authorities said.Officials first said as many as 30 motorists might have been burned after being trapped in vehicles overwhelmed by the quick-moving flames and smoke.
At least 20 cars could be seen actively burning on the roadway.

The vehicles include a semi truck and car carrier. Officials said 10 vehicles were damaged. Several water-dropping aircraft have tried to extinguish fires in the vehicles. Authorities have now downplayed reports of burn injuries but said ambulances were dispatched to the area. Late Friday, officials said there were two minor injuries reported. They did not say if they included burns. MORE
