Bright lights in the night sky sparked UFO alerts in Saudi Arabia, but the display turned out to be a well-known space phenomenon: the fiery re-entry of some Chinese space junk. Multiple videos of Thursday nights lights were posted on YouTube. One sighting was reported by a witness who was near the Prophets Mosque in the western Saudi city of Medina, according to reports from the Saudi newspaper Al Sada and the Emirates24/7 website." I was passing just near the mosque when I saw the object ... I captured a film of it, but I could not trace it as it split into two or three parts," Al Sada quoted Fahd Al Harbi as saying. via NBC News.com.
