According to information released by Egyptian officials the eight Americans were initially transferred to a military hospital for treatment and then 10 of the injured tourists, which included two Egyptians, were airlifted to a hospital in Cairo.
Officials report that the tour bus was part of a larger tour involving some 116 passengers on three buses. The remaining two buses did not continue to Abu Simbel, but returned to Asawan instead.
According to a report on CBSNews.com, the U.S. embassy in Cairo has confirmed that the injured were being moved by military transport to Cairo, but said in a statement that it didn't have any further information on the accident or those involved.
