Fire officials say about 500 students evacuated safely after a holiday decoration on a teacher’s desk ignited at a private school in Las Vegas. Las Vegas fire spokesman Tim Szymanski (zim-ANN’-skee) there were no injuries in the 9 a.m. Tuesday fire, which was confined to the desk in a room at the Cornerstone Christian Academy & Tyke’s Preschool on the city’s west side. An automatic fire sprinkler system doused the flames. Szymanski says students in grades preschool to eight were moved to a chapel on part of the school campus away from the classroom.
